Adolescence is a phase of life of a person when he is no more a child and not yet adult. The life is full of tremendous energy. The curiosity and experimentation at one time paves the path to success and at other, may cause uncertainty. This is a critical time in life because the experiences, knowledge and skills acquired in adolescence have important implications in adulthood.

Key PointsAdolescents need to find their place in society and gain a sense of fitting in it. This is a process of socialization involving an adolescent’s integration with society. This process socialization enhances the sense of personal identity, and the development of personal identity helps the adolescent to deal with society’s expectations and standards and norms. This challenges the adolescent to make changes in social behaviour.

Society’s expectations pose a challenge for adolescents and are valuable in helping them to progress along the path to adulthood. The fulfilment of these expectations helps to develop a positive sense of self.
Adolescents who are over-whelmed by society’s expectations may revert to anti-social behaviour ranging from low-level delinquency to serious crimes.
Parental expectations to perform and confirm to their standards are abnormally high or unrealistic. They may generate negative feelings, communication gap and anti-social behaviour.
Adolescent expectations in relationships with peers, parents and society are often not fulfilled and cause conflicts.
Moving away from dependence on parents and family and having close relationships with friends is a major social change. Parental control leads to conflicts and communication gap. Peers determine the flow of an adolescent’s life and develop their personality too.

Hence, it can be concluded that 'Relationship with parents'can have a significant impact on the social competence of an adolescent.

For civilization to continue and operate, socialization is a critical process. Varied civilizations have different practices and procedures for educating their newborn members so that they can grow into unique individuals. Socialization is the term used to describe the personality development and training of the youngster.

Key PointsSome of the definitions of socialization are as follows:-

Tony Bilton: “The process by which we acquire the culture of the society into which we are born - the process by which we acquire our social characteristics and learn the ways of thought and behavior considered appropriate in our society - is called socialization”.
Anthony Giddens: “Socialisation refers to the process which transforms a quite helpless human infant into a self-aware, knowledgeable person who is skilled in the ways of their society’s culture”.
Peter Worsley:” By this is meant, simply, the transmission of culture, the process whereby men learn the rules and practices of social groups. Socialisation is an aspect of all activity within all human societies”.

Hence, it is concluded that Tony Bilton said“The process by which we acquire the culture of the society into which we are born - the process by which we acquire our social characteristics and learn the ways of thought and behavior considered appropriate in our society - is called socialization”

Skinner is a behaviorist who is responsible for giving the operant conditioning theory. Based on his theory he gave the laws if learning.

Key Points

Skinner gave the concept of operant conditioning which states the role of reinforcers in the development of learning.
He believes that learning is not instant and is accompanied by the shaping of behavior.
Shaping refers to the development of behavior through a gradual process.
He believed that positive reinforcers or reward leads to the strengthening of behavior and negative reinforcers lads to a diminishing effect.

Hence, we conclude that according to Skinner, the development of a learner is a continuous and gradual process.

Psychologyis the scientific study of the mind and behavior. Psychology is a multifaceted discipline and includes many sub-fields of study such areas as human development, sports, health, clinical, social behavior, and cognitive processes.

Important PointsExperimental method:Experiments are generally conducted to establish a cause-effect relationship between two sets of events or variables in a controlled setting

The experimental methodis the most scientific and objective way of studying behavior.
In this method, experiments are conducted in the laboratories under controlled conditions.
In experiments, usually, the effect of the independent variable on the dependent variable is studied.
There will be two variables, viz., Independent and dependent variables.
For example,the effect of music on the level of blood pressure can be studied in laboratory settings. Here, the music is the independent variable and the BP is a dependent variable.

Key PointsImportant methods of Studying Human Behavior are as follows:

Introspection Method
Observation Method
Experimental Method
Clinical Method/Case History Method

Thus, it is concluded thatthemost scientific and objective method of studying behavior istheExperimental method.

Hint

Introspection Method:This method was introduced by EB Titchener. This is also known as the self-observation method. Introspection means ‘to look within'. It is not possible to understand the inner feelings and experiences of other persons. But the individual himself can observe and report.
Observational method:This method is very useful in areas where experiments cannot be conducted. In this method, the observer will observe and collect the data. Example: In the hospital, the nurse will make observations of patient’s temperature, pulse, BP, facial expressions, etc.

The guiding principles of a school's curriculum are the ideals that it feels will provide its students and community the best chance of success and are appropriate in the circ*mstances.

Key Points

The curriculum should be child-centered because contemporary education is. It ought to be determined by the child's requirements, interests, skills, ability, age, and environment.
The curriculum should be flexible.
The curriculum's subject matter cannot stay the same forever. It must not be stagnant. It needs to be dynamic and adapt to the times.
Utilitysays that the subject or topics that are useful to the learner should be in the curriculum.

Hence, it is concluded that the following are the principles of curriculum construction except for conservative.

The correct answer is Nakula - Digvijyams.

Rohtak derives its name from its headquarters town, Rohtak, which is called the Reformation of Rohtashgarh, a name still applied to the ruined sites of the two old sites.
- Traditionally, it is named after King Rohtash, in whose days the city is said to have been built.
- It is also claimed that the city derives its name from the Roherra (Tacoma undulate) tree which is called Rohitaka in Sanskrit.
- It is said that before the city came into existence, it was the site of a forest of Rohitaka trees and hence the name Rohtak.
- Another version links Rohtak with Rohitaka, which is mentioned in the Mahabharata in connection with the campaign of the Pandava warrior Nakula.

Additional Information

Divyavadana (meaning Divine Tales) is a text of Buddhist tales.
- The origin of many of these stories is the original Mool Sarvastivada Vinaya Granth.
Majjima Nikaya is a Buddhist text, the second of the five Nikayas or collections in the Sutta Pitaka, one of the 'three baskets' that compose the Pali Tipitaka of Theravada Buddhism. Composed between the 3rd century BCE and the 2nd century CE.

Traditional teaching techniques have been put to the test by a variety of technologically advanced teaching and learning approaches along with technological advancement.

Key Points

Kids today are immersed with technology from a very young age. With the aid of technology, the education system is also changing
The use of technology transforms the teacher's position from that of a traditional knowledge supplier into that of a facilitator, leading the learning processes of the students and engaging in collaborative problem-solving with them.
Even now, students may quickly get content information. In the upcoming ten years, more people will use the internet to get information.
As a result, the teacher's job will no longer just involve giving pupils knowledge; it will involve guidingthem in selecting the relevant information from a bundle of data.

Hence, it is concluded that with the development of technology, the role of the teacher in the future will be to guidethe students.

The teacheris a veryimportantcomponentof the teaching-learning process. The teacher has to playdifferent rolesin order tofacilitate the learningprocess and to providedirect and real-life experiences to learners.

Thestudent's learning paceor performance level getshighly influenced by the teacher's activities. The teacher aims to develop the holistic personality of a student.
Theteacheris afacilitator, as hisroleis to create such an atmosphere of learning where the children can themselves realize theirtrue potential and can construct knowledge.

Key Points

The different roles of a teacher:

While organizing an activity in the classroom for students to have hands-on experience, the role of the teacher is tosupervise students and provide guidance wherever required.

Confusion Points

ask students to carry out the activity strictly as per the instruction given: This will hinder the creativity of the child in the classroom. The child will not be able to construct knowledge on his own if s/he is following the instructions strictly.

give all the freedom to students to carry out the activity on their own: In this case, the student will not be able to resolve his doubts and misconception without the teacher that will arise during the activity.

instruct constantly so that students achieve their results without making any mistakes: In this case, the children will not get any space to construct the knowledge and show his/her creativity.

Lev Vygotskyis a Russian Psychologistwho proposed the theory ofSocio-cultural development. In this theory, Vygotsky emphasizes the role ofsociety and culturein the development of the child.

Key Points Vygotsky also proposed three basic needs of students during learning, these are:

ZPD (zone of proximal development): The difference between the learning of a child by self and the learning of a child with the help of others(society, culture, etc).
Scaffolding: Scaffolding is the term, given by Vygotsky, in which he proposed that thetemporaryhelp given by the teachers, family, friends, etc. to the children in his learning.
- When students enter the lab for the first time, the teacher assists them in identifying the equipment. Lev Vygotsky claimed that the teacher's role symbolizes scaffolding.
MKO (more knowledgeable others)-Vygotsky defined the “More Knowledgeable Other” (MKO) as anyone who has a better understanding or a higher ability level than the learner, particularly in regard to a specific task, concept, or process. MKO could be teachers, parents, tutors, and even peers.

As a result, the teacher helps the students identify the equipment when they enter the lab for the first time. According to Lev Vygotsky, the role of the teacher represents a Scaffoldingperson.

Important Points According to Vygotsky, there are three main factors that affect the learning of the child and these are- Social interaction, Culture, and Language:

Social interaction:Childrentry tointeractwithpeople.
- Example: Peer groups, family members, etc.
Culture:Childrenadopt the culture through interaction.
Language:Children can easily intimate their primary language through interaction or communication.

The Principal is part or head of a school whose function is to support and assist the school in meeting the overall objectives of the Division and the needs of individual students. The role of the Principal is to provide leadership, direction, and coordination within the school.

Important Points

The teacher is the role model of the students.
Being a teacher, there are a lot of duties and responsibilities.
If the principal is assigning certain duties to the teacher, then it is the teacher's duty to accept them.
The teacher must do that duty delegated and efficiently.

Key Points

The most common cause of fainting in otherwise healthy youngsters is a short interruption in the passage of oxygen-rich blood to the brain (blood pressure). The child usually recovers rapidly. This is referred to as simple fainting.
As a principal, if a child faints during school prayer, itis your responsibility to take care of the child and supervise the first aid to the child and resume the prayer.Apart from this, the child will not be disturbed and the fanned children will also get first aid. After that, we can take her to the doctor.

Thus it is clear that as a principal you ask a teacher to continue with prayer, supervise the first aid to the child, and resume the prayer.

What does it mean when you see a yellow traffic light?

" }, "answerExplanation": { "@type": "Comment", "text": "

When you see a yellow traffic light, it indicates that the signal is about to change from green to red. Drivers should proceed with caution and be prepared to stop if necessary. The yellow light serves as a warning to drivers to slow down and prepare to come to a stop. It's essential to exercise caution and make a safe decision based on the traffic conditions at the intersection. Speeding up to pass through the intersection or ignoring the light can lead to accidents and traffic violations.

Additional Fact:
Yellow traffic lights are designed to provide drivers with a transition period between the green and red phases of the signal. This allows for a smooth flow of traffic while ensuring safety at intersections. Drivers should use this time to assess the situation, decide whether it's safe to stop, and proceed accordingly.

The child-centered approach is different from the traditional approaches. Here the child is considered to be more important than the teacher. The teacher just plays the role of a facilitator providing students the opportunity to explore.Key Points

The teacher tries to motivate the learner before he/she starts the teaching-learning process.
The teacher is a facilitator in the teaching-learning process and not an instructor.
A situation is created for facilitating the learning process.
Students work both individually and in groups.
Students learn from interaction with their peers.
Opportunities are provided to the students for questioning, exploration and experimentation.
The seating arrangement is guided according to the activities of the students in the classroom.
Assessment is a part of the teaching-learning process and children are assessed in course of doing the activities. So learning process and assessment go together.
A variety of teaching-learning materials are used which are manipulated by the teacher and the students.
The learning climate is democratic.

Students often ask questions to the teachers for clarity of concepts.

Hence, in a child-centeredclassroom teacher provides learning situations that allow students to observe, explore, question, experience, and develop an understanding of various concepts.

Hint

The teacher gives instructions and expects students to obey and be disciplined
The teacher reads the textbook, writes questions and answers on the blackboard, and asks students to copy them
The teacher controls what happens in the classroom and students' participation is minimal

The above three aredone in teacher-centered classrooms where the teacher stays active and students are passive having no chance to explore or ask questions.

A child’s development is indicated by physical growth (rapid growth in height), speech and language development (being able to read and write) or development of gross motor skills (motor coordination). But a child’s social maturity is indicated byhis/her ability to be aware of the presence of others and to interact with other children and adults.

Important PointsSocial maturity is the ability of an individual by which he/she displays an appropriate responsible behaviour. Itis an important aspect of society and as well as individuals.Social maturityis essentially a matter ofintegration of one's purposes with those of the social order.

Key Points

An important indication of a child's social maturity is awareness of the presence of othersas social maturityrefers to:

thedevelopment of social skills and valuesin an individual across the lifespan.

theindividuals' ability to act and respondaccording to the circ*mstances and culture of the society.

the way anindividual adapts social norms, values, culture,etc. and internalizes the attitudes and customs of society.

Hence, it could be concluded that an important indication of a child's social maturity is awareness of the presence of others.

" }, "answerExplanation": { "@type": "Comment", "text": "

Explanation of Highest Value of Oxidation Number Changes from 1 to 7

The highest value of oxidation number changes from 1 to 7 across the third period in the periodic table. This is due to the following reasons:

The Atoms of Transition Elements:Transition metals are those elements located in the d-block of the periodic table. They have varying oxidation states, but they do not usually reach an oxidation state of 7. Their oxidation states primarily range between +2 and +3, although some can reach states of +4 or +5.
The First Three Groups:The first three groups of the periodic table include alkali metals, alkaline earth metals, and boron group elements. These groups generally have oxidation states of +1, +2, and +3 respectively. They do not reach an oxidation state of 7.
In Alkaline Earth Metals:Alkaline earth metals are the elements in the second group of the periodic table. These elements generally have an oxidation state of +2 due to the presence of two valence electrons which are readily lost in chemical reactions.
Across the Third Period in the Periodic Table:The elements in the third period of the periodic table show a wider range of oxidation states, which can vary from +1 to +7. This is due to the presence of both s and p orbitals in their valence shell, which allows the elements to lose or gain more electrons in chemical reactions. Therefore, across the third period in the periodic table, the highest value of oxidation number changes from 1 to 7.

Which of the following conversions involve ATP synthesis during glycolysis?

" }, "answerExplanation": { "@type": "Comment", "text": "

In the energy conserving phase of glycolysis, the conversion of BPGA to PGA is catalyzed by phosphoglycerate kinase. The phosphate on carbon 1 is transferred to a molecule of ADP, yielding ATP and 3-phosphoglycerate. This type of ATP synthesis, traditionally referred to as substrate-level phosphorylation, involves the direct transfer of a phosphate group from a substrate molecule to ADP, to form ATP.

Bryophytes include three distinct groups of plants:

1) Mosses

Mosses are small, non-vascular plants that typically form dense green clumps or mats, often in damp or shady locations.

2) Liverworts

Liverworts are another type of non-vascular plants and are similar to mosses. They are named for their lobed, liver-like appearance.

3) Hornworts

Hornworts are a group of non-vascular plants constituting the division Anthocerotophyta.

Ferns are not included in the bryophyte group. They are vascular plants that have alternating generations and use spores for reproduction. They are part of a different group called Pteridophytes.

Hence, the correct answer is C: Mosses and Liverworts. This is because both mosses and liverworts are included in the bryophyte group, while ferns are not.

Liverworts are a group of non-vascular plants similar to mosses.
They are unlike most plants we are familiar with because they don't produce seeds, flowers, fruit, or wood, and they don't even have vascular tissue.
For reproduction, liverworts create spores instead of seeds. The bryophytes are divided into liverworts and mosses. So they are closely related to each other.

Fig: Mosses
Hence, the correct option is B.

μ=sinisinr

Again for minimum deviation

μ=sin(A+δmin2)sinA2

∴μ=sinisinA2

⇒sinA2=siniμ

⇒sinA2=sin45∘√2=12

⇒A2=30∘

⇒A=60∘

Againi+e=A+δmin

For minimum deviationi=e

∴2i=A+δmin

⇒δmin=2i−A

⇒δmin=2×45∘−60∘=30∘

Ionization isomers are identical except that a ligand has exchanged places with anion or neutral molecule that was originally outside the coordination complex.
Thus, in Ionization isomerism the central ion and the other ligands are identical.
So, according to the definition, Cl^-is replaced by NO^2-in the ionization sphere.
[Cr(H₂O)₄Cl(NO₂)Cl] ----> [Cr(H₂O)₄Cl(NO₂)]⁺+ Cl^-
[Cr(H₂O)₄Cl₂]NO₂-----> [Cr(H₂O)₄Cl₂]⁺+ NO₂^-

Biotic potential is defined as the physiological capacity of organisms to produce their offspring under natural conditions. It is also called reproductive potential. In nature, the biotic potential of organisms is enormous but all the organisms do not survive due to the lack of food and space. There are also a number of diseases and the predatory organisms, that feed upon other organisms. The carrying capacity is the maximum number of individuals which the environment can support or sustain.

Wavelength of light beam,λ

Distance of the screen from the slit,D=1m

For first minima,n=1

Distance between the slits isd

Distance of the first minimum from the centre of the screen can be obtained as,x = 2.5mm = 2.5×10⁻³

Now,nλ = xd/D

⇒ d= nλD/x = 0.2mm

Therefore, the width of the slits is 0.2 mm.

A fruit is the seed- bearing structure in flowering plants also referred to as angiosperms produced from the ovary after flowering. Rather, in some fruits, it is not the ovary that produces the fruit. In fact, other parts of the flower, just like the thalamus, inflorescence, and calyx are modified to become an area of the fruit.

HSSC TGT Science Mock Test - 9 - Question 1

Save

BOD of safe drinking water should be

A.
Nil
B.
10 ppm
C.
20 ppm
D.
30 ppm

Detailed Solution for HSSC TGT Science Mock Test - 9 - Question 1

Concept:

The biochemical oxygen demand of safe drinking water is zero.

BOD represents the amount of biodegradable organic matter present in water. It also indicates the amount of treatment required for purifying. If the BOD is high the extent of treatment required will be high.

Hence, thereshould not be any BOD in safe drinking water.

Detailed Solution for HSSC TGT Science Mock Test - 9 - Question 2

The correct answer isTertiary Treatment.

Concept:

Sewage treatment is the process of cleaning polluted water before it is discharged into bodies of water.

Explanation:

Sewage water treatment is carried out in three stages:

Primary treatment:

This involves the physical removal of particles from the sewage through filtration and sedimentation.
Floating debris is initially removed through sequential filtration.
Then the grit is removed by sedimentation.
The settled solids from the primary sludge and the supernatant from the effluent.

Secondary treatment:

The primary effluent is passed in aeration tanks and constantly agitated mechanically.
Air is pumped into it.
This promotes the growth of beneficial aerobic microbes that consume organic matter in the effluent.

Tertiary treatment:

It is the advanced treatment process that follows secondary wastewater treatment and produces high-quality water.
Tertiary treatment of wastewater includes the removal of nutrients such as phosphorus and nitrogen, as well as removing all suspended and organic matter.

Which of the following is not a factor in soil formation?

A. Soil composition
B. Parent rock
C. Time
D. Climate

Detailed Solution for HSSC TGT Science Mock Test - 9 - Question 10

The correct answer issoil composition.

Key Points

Soil compositionis not a factor in soil formation.
The soil is a mixture that contains minerals, organic matter, and living organisms.
Soil is one of the most important elements of an ecosystem, and it contains both biotic and abiotic factors.
The composition of abiotic factors is particularly important as it can impact the biotic factors, such as what kinds of plants can grow in an ecosystem.

Additional InformationFactors responsible of soil formations

Soils are formed through the interaction of five major factors: time, climate, parent material, topography and relief, and organisms.
The relative influence of each factor varies from place to place, but the combination of all five factors normally determines the kind of soil developing in any given place
Time-The formation of soils is a continuing process and generally takes several thousand years for significant changes to take place.
Climate, particularly temperature, precipitation and frost action have a profound influence on the soil forming processes which occur within a region.
Parent material is the unconsolidated mineral and organic deposits in which soils are developing.
It determines the mineralogical composition and contributes largely to the physical and chemical characteristics of the soil.
Topography-The shape of the land surface, its slope and position on the landscape, greatly influence the kinds of soils formed.

The property of a soil which permits water to percolate through it, is called __________.

A. Moisture content
B. Permeability
C. Capillarity
D. None of these

Detailed Solution for HSSC TGT Science Mock Test - 9 - Question 11

Moisture content is the ratio of mass of water to mass of soil solids. It may be greater than 100 %.

Permeability of soil is the property of the soil withhow much ease water can flow through the soil mass. Higher the easiness of flowing the water, higher the permeability of soil sample. Generally, coarse grained soils like sand have higher permeability than that of fine grained soils like clay.

Capillarity is the phenomena due to which water can rise and filled the air voids of partially or fully dried soil mass due the action of surface tension forces. The smaller the air void size, the higher the water rises in thesoil.

This means that claysoilallows water to raise more as compared to sand.

Percolationis defined as the slow movement of water through the pores insoilor permeable rock.

A. Relationship with parents
B. Reasoning in classrooms
C. Response to situations
D. Recreational activities

Detailed Solution for HSSC TGT Science Mock Test - 9 - Question 35

Society’s expectations pose a challenge for adolescents and are valuable in helping them to progress along the path to adulthood. The fulfilment of these expectations helps to develop a positive sense of self.
Adolescents who are over-whelmed by society’s expectations may revert to anti-social behaviour ranging from low-level delinquency to serious crimes.
Parental expectations to perform and confirm to their standards are abnormally high or unrealistic. They may generate negative feelings, communication gap and anti-social behaviour.
Adolescent expectations in relationships with peers, parents and society are often not fulfilled and cause conflicts.
Moving away from dependence on parents and family and having close relationships with friends is a major social change. Parental control leads to conflicts and communication gap. Peers determine the flow of an adolescent’s life and develop their personality too.

Hence, it can be concluded that 'Relationship with parents'can have a significant impact on the social competence of an adolescent.

D. Differential method

Detailed Solution for HSSC TGT Science Mock Test - 9 - Question 41

Important PointsExperimental method:Experiments are generally conducted to establish a cause-effect relationship between two sets of events or variables in a controlled setting

The experimental methodis the most scientific and objective way of studying behavior.
In this method, experiments are conducted in the laboratories under controlled conditions.
In experiments, usually, the effect of the independent variable on the dependent variable is studied.
There will be two variables, viz., Independent and dependent variables.
For example,the effect of music on the level of blood pressure can be studied in laboratory settings. Here, the music is the independent variable and the BP is a dependent variable.

Key PointsImportant methods of Studying Human Behavior are as follows:

Introspection Method
Observation Method
Experimental Method
Clinical Method/Case History Method

Thus, it is concluded thatthemost scientific and objective method of studying behavior istheExperimental method.

Hint

Introspection Method:This method was introduced by EB Titchener. This is also known as the self-observation method. Introspection means ‘to look within'. It is not possible to understand the inner feelings and experiences of other persons. But the individual himself can observe and report.
Observational method:This method is very useful in areas where experiments cannot be conducted. In this method, the observer will observe and collect the data. Example: In the hospital, the nurse will make observations of patient’s temperature, pulse, BP, facial expressions, etc.

Detailed Solution for HSSC TGT Science Mock Test - 9 - Question 46

Lev Vygotskyis a Russian Psychologistwho proposed the theory ofSocio-cultural development. In this theory, Vygotsky emphasizes the role ofsociety and culturein the development of the child.

Key Points Vygotsky also proposed three basic needs of students during learning, these are:

ZPD (zone of proximal development): The difference between the learning of a child by self and the learning of a child with the help of others(society, culture, etc).
Scaffolding: Scaffolding is the term, given by Vygotsky, in which he proposed that thetemporaryhelp given by the teachers, family, friends, etc. to the children in his learning.
- When students enter the lab for the first time, the teacher assists them in identifying the equipment. Lev Vygotsky claimed that the teacher's role symbolizes scaffolding.
MKO (more knowledgeable others)-Vygotsky defined the “More Knowledgeable Other” (MKO) as anyone who has a better understanding or a higher ability level than the learner, particularly in regard to a specific task, concept, or process. MKO could be teachers, parents, tutors, and even peers.

As a result, the teacher helps the students identify the equipment when they enter the lab for the first time. According to Lev Vygotsky, the role of the teacher represents a Scaffoldingperson.

Important Points According to Vygotsky, there are three main factors that affect the learning of the child and these are- Social interaction, Culture, and Language:

Social interaction:Childrentry tointeractwithpeople.

The teacher is the role model of the students.
Being a teacher, there are a lot of duties and responsibilities.
If the principal is assigning certain duties to the teacher, then it is the teacher's duty to accept them.
The teacher must do that duty delegated and efficiently.

Key Points

The most common cause of fainting in otherwise healthy youngsters is a short interruption in the passage of oxygen-rich blood to the brain (blood pressure). The child usually recovers rapidly. This is referred to as simple fainting.
As a principal, if a child faints during school prayer, itis your responsibility to take care of the child and supervise the first aid to the child and resume the prayer.Apart from this, the child will not be disturbed and the fanned children will also get first aid. After that, we can take her to the doctor.

Assessment is a part of the teaching-learning process and children are assessed in course of doing the activities. So learning process and assessment go together.
A variety of teaching-learning materials are used which are manipulated by the teacher and the students.
The learning climate is democratic.

Students often ask questions to the teachers for clarity of concepts.

Hence, in a child-centeredclassroom teacher provides learning situations that allow students to observe, explore, question, experience, and develop an understanding of various concepts.

Hint

The teacher gives instructions and expects students to obey and be disciplined
The teacher reads the textbook, writes questions and answers on the blackboard, and asks students to copy them

Detailed Solution for HSSC TGT Science Mock Test - 9 - Question 55

Explanation of Highest Value of Oxidation Number Changes from 1 to 7

The highest value of oxidation number changes from 1 to 7 across the third period in the periodic table. This is due to the following reasons:

The Atoms of Transition Elements:Transition metals are those elements located in the d-block of the periodic table. They have varying oxidation states, but they do not usually reach an oxidation state of 7. Their oxidation states primarily range between +2 and +3, although some can reach states of +4 or +5.
The First Three Groups:The first three groups of the periodic table include alkali metals, alkaline earth metals, and boron group elements. These groups generally have oxidation states of +1, +2, and +3 respectively. They do not reach an oxidation state of 7.
In Alkaline Earth Metals:Alkaline earth metals are the elements in the second group of the periodic table. These elements generally have an oxidation state of +2 due to the presence of two valence electrons which are readily lost in chemical reactions.
Across the Third Period in the Periodic Table:The elements in the third period of the periodic table show a wider range of oxidation states, which can vary from +1 to +7. This is due to the presence of both s and p orbitals in their valence shell, which allows the elements to lose or gain more electrons in chemical reactions. Therefore, across the third period in the periodic table, the highest value of oxidation number changes from 1 to 7.

1) Mosses

Mosses are small, non-vascular plants that typically form dense green clumps or mats, often in damp or shady locations.

2) Liverworts

Liverworts are another type of non-vascular plants and are similar to mosses. They are named for their lobed, liver-like appearance.

3) Hornworts

Hornworts are a group of non-vascular plants constituting the division Anthocerotophyta.

Ferns are not included in the bryophyte group. They are vascular plants that have alternating generations and use spores for reproduction. They are part of a different group called Pteridophytes.

Hence, the correct answer is C: Mosses and Liverworts. This is because both mosses and liverworts are included in the bryophyte group, while ferns are not.

Lichen
B.
Mosses
C.
Algae
D.
Fungi

Detailed Solution for HSSC TGT Science Mock Test - 9 - Question 71

Liverworts are a group of non-vascular plants similar to mosses.
They are unlike most plants we are familiar with because they don't produce seeds, flowers, fruit, or wood, and they don't even have vascular tissue.
For reproduction, liverworts create spores instead of seeds. The bryophytes are divided into liverworts and mosses. So they are closely related to each other.

Fig: Mosses
Hence, the correct option is B.
