HTET TGT Science Mock Test - 7 - HTET MCQ

Critical pedagogy includes relationships between teaching and learning. Its proponents claim that it is a continuous process of what they call unlearning, learning, and relearning, reflection, evaluation, and the impact that these actions have on students. Critical pedagogy is a philosophy of education and social movement that combines education with critical theory. Paulo Freire was the first to describe it.
Freire endorses students' ability to think critically about their educational situation; this way of thinking allows them to recognize connections between their individual problems and experiences and the social contexts in which they are embedded.

Heredity and Environment operate together to produce a person's intelligence, temperament, height, weight, etc. The relative contributions of heredity and environment are not additive. It cannot be said that such-and-such percentage of nature, and such-and-such percentage of experience makes us who we are. The genetic expression also does not happen just once. Genes produce proteins throughout the lifespan, in many different environments.

A student of any class having a problem of  'visual deficiency' should be treated normally within the classroom and provided support through audio CDs. Children suffering from 'visual deficiency are unable to see, in that case, they should be provided adequate support through audio lectures so that they also gain the same level of understanding as other students.
Hence, the correct answer is, 'Treated normally in the classroom and provided support through audio CDs.'

Jean Piaget has proposed four stages in his cognitive development theory. The First stage is the sensorimotor stage which occurs from birth to 2 years, second is the pre-operational stage which occurs from 2 to 7 years of age, the third is the concrete operational stage which occurs from 7 to 11 years of age. This is the stage when a child begins to think logically about objects and events. Last is the formal operational stage which occurs above 12 years of age.
Hence, the correct answer is, 'Concrete operational stage.'

The 'insight theory of learning' was proposed by Wolfgang Kohler. During the time when he was studying the behaviour of apes, he has designed some simple experiments that lead to the development of the cognitive theories of learning which he referred to as insight learning.
Insight learning is the form of cognitive learning in which animals are used by Kohler to get the results. It occurs in human learning when people recognize relationships that can help them in solving problems.
Hence, the correct answer is, ''Gestalt theorists.'

Jean Piaget has proposed the cognitive development of theory in which he identified four stages of children's intellectual development. These stages are, the sensorimotor stage which occurs from birth to 2 years, the preoperational stage which occurs from 2 years to 7 years, the concrete operational stage which occurs from 7 years to 11 years and the formal operational stage (abstract thinking) which occurs from 11 years and above.
Hence, the correct answer is, 'Piaget.'

Special education is defined as individualized educational instruction designed to meet the unique educational and related needs of students with disabilities. 

Kohlberg's theory of moral development is a theory that focuses on how children develop morality and moral reasoning. His theory played a profound role in the development of moral psychology.

"Motivation" refers to the factors that move or activate the behavior of people toward a goal. It plays a significant role in students learning and development.
For example, when we see a student working diligently on every duty assigned to him or her, hence we infer that the individual has a motive to achieve. According to Skinner, "motivation is the superhighway to learning".

Many times fish culture also known as pisciculture done in combination with rice crop. 

this is because during the sowing of rice crop it needs more and more water . the land where to sown the rice crop should be too much wet . even the field is filled with water up to 1 to 1.5 feet . so , in this water we can rear the fish also cause water is enough for fish and rice too. 

this water helps to. survive the new fishes in the field and when this fishes grown up than it will be transfer to a big lake or a pond . 

Brownian movement arises because of the impact of the molecules of the dispersion medium with the colloidal particles. Since the impacts of the molecules of the dispersion medium on the colloidal particles are unequal (i.e. unbalanced bombardment), the result is zig-zag motion.

Arteries are thick-walled blood vessels which pump blood at high pressure away from the heart. They do not have valves as their walls are highly muscular.

Food Chain: Starting Point
The correct answer to the question is B: Photosynthesis. A food chain always starts with photosynthesis. Here is a detailed explanation of why photosynthesis is the starting point of a food chain:
1. What is Photosynthesis?
Photosynthesis is the process by which green plants, algae, and some bacteria convert sunlight, water, and carbon dioxide into glucose and oxygen. It takes place in the chloroplasts of plant cells.
2. Role of Photosynthesis in the Food Chain:
Photosynthesis is the primary source of energy for all living organisms on Earth. It is responsible for the production of organic compounds, primarily glucose, which serves as food for the entire food chain.
3. Producers:
Green plants, also known as producers, are the first trophic level in a food chain. They use photosynthesis to convert sunlight energy into chemical energy (glucose). They are self-sustaining and do not depend on other organisms for their energy.
4. Herbivores:
Herbivores are the primary consumers in a food chain. They consume plants, utilizing the energy stored in the glucose produced through photosynthesis. Examples of herbivores include cows, rabbits, and deer.
5. Carnivores and Omnivores:
Carnivores and omnivores are the secondary and tertiary consumers in a food chain. They obtain energy by consuming herbivores or other carnivores. Carnivores solely depend on the consumption of other organisms for their energy needs.
6. Decomposers:
Decomposers, such as bacteria and fungi, play a crucial role in the food chain. They break down the remains of dead organisms, including plants and animals, releasing nutrients back into the ecosystem. These nutrients are then used by plants for photosynthesis, completing the cycle.
In conclusion, photosynthesis is the starting point of a food chain. It provides the energy needed for the growth and survival of all living organisms in an ecosystem. Without photosynthesis, the food chain would cease to exist, and life on Earth would not be sustainable.

The key difference between strong acids and weak acids lies in their degree of dissociation in water. Strong acids dissociate completely or almost completely in water, resulting in a higher concentration of hydrogen ions. On the other hand, weak acids only partially dissociate, leading to a lower concentration of hydrogen ions compared to strong acids. This difference in dissociation behavior is what distinguishes strong acids from weak acids.

A pH value greater than 7 signifies a basic solution. This indicates that the concentration of hydroxide ions (OH-) in the solution is higher than the concentration of hydrogen ions (H+), making the solution basic in nature. Basic solutions have a pH greater than 7 and can range from slightly basic to strongly basic.

Explanation: Aluminum is ductile and has a high electrical conductivity, which makes it unsuitable for utensil production. Aluminium has a high melting point and good heat conductivity. Copper, steel (an alloy of iron), and aluminium are the most popular metals used to make utensils. Due to their ability to conduct heat, copper and aluminium are the most used materials.

• Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. 
• Acceleration is a vector quantity that is defined as the rate at which an object changes its velocity.
• Velocity is a vector quantity that refers to the speed of an object in a particular direction.

The greater the valency of the element, the greater is its unreactivity. Also, the valency in a period increases from the left to the middle, then again decreases from middle to the right. So we can say that the unreactive elements are located in the center of the period. Since phosphorus and Silicon are located at the center, they have the highest number of Valence electrons, and hence are the most unreactive in the period.
