Answer: C

Explanation:
The word that is different from the rest is Scallop (C). The reasons are as follows:
- Oyster (A), Clam (B), and Mussel (D) are all bivalve mollusks, meaning they have a shell that is divided into two hinged parts. On the other hand, Scallop (C) is also a bivalve mollusk, but it has some unique features that set it apart.
- Scallop's unique features:
- Scallops have a distinct shell shape, which is rounder and flatter compared to the other three.
- Scallops have an ability to swim by opening and closing their shells rapidly, which is not a common feature among the other three mollusks.
- The adductor muscle of the scallop, the part that is commonly consumed, is larger and more developed than in oysters, clams, or mussels, making it a more popular choice for culinary dishes.
These differences make Scallop (C) the word that stands out from the rest.All except Scallop, live in shells.

As per the given information;

Four friends W, X, Y and Z are students of Class 10th.

i) W and X are good in Hindi but poor in English.

ii) W and Y are good in Science but poor in Mathematics.

iii) Y and Z are good in English but poor in Social Studies.

iv) Z and X are good in Mathematics as well as in Science.

Thus we can see W is not good in Mathematics but good in Hindi.

Hence, the correct answer is "W".

By using the symbols in the table given below, we can draw the following family tree:

We do not know the gender of Shanti. 
Clearly, Shaurya is the cousin of Karan.
Hence, ‘Cousin’ is the correct answer.

The pattern followed is:

Hence, the correct answer is "127".

Alternate Method
The pattern followed is:
3 = 2² - 1
7 = 2³ - 1
15 = 2⁴ - 1
31 = 2⁵ - 1
63 = 2⁶ - 1
127 = 2⁷ - 1
Hence, the correct answer is "127".

The logic followed here is:

In figure 1:

32 = (2 + 2) × 8

4 × 8

32

In figure 2:

24 = (3 + 1) × 6

4 × 6

24

Similarly,

In figure 3:

45 = (4 + ?) × 5 

4 + ? = 9

? = 9 - 4

? = 5

Hence, the correct answer is "5".

Given:

The ratio of the present age of Annu and Raj = 4 : 5

Then after 8 years ratio of their age = 5 : 6

Calculation:

Let be assume the present age of Annu and Raj is 4x and 5x respectively

⇒ (4x + 8)/(5x + 8) = 5/6

⇒ 24x + 48 = 25x + 40

⇒ x = 8

⇒ The age of Annu = 4x = 4 × 8 = 32

⇒ The age of Raj = 5x = 5 × 8 = 40

∴ The required result will be 32 years, and 40 years respectively.

Scaffolding process in education is a teaching strategy to expedite children's learning process. Using this method, teachers first demonstrate how to deal a problem, then go back and offer support as and when required. Once basic learning is done, they give prompts, ask questions, cues to make the child learn and build the concept on what he has already learned.

The way in which students bring their finding to others and apply their understanding to new and unfamiliar circumstances, grows out of excitement for what they have accomplished. Student would be excited to reveal his finding.

The communication ability of a teacher helps her to establish a rapport with the students. A teacher who is a good communicator can understand the dilemma of students, and can effectively solve their problems.

Teachers use different evaluation methods because different subjects require different methods of assessment like science can be assessed by practical exams and languages can be assessed by evaluating verbal ability and fluency.

The first law of thermodynamics states that the total energy of an isolated system is constant. Energy can be transformed from one form to another, but can neither be created nor destroyed.

According to this law, some of the heat given to system is used to change the internal energy while the rest in doing work by the system. Mathematically,

ΔQ=ΔU+ΔW

where,

ΔQ =  Heat supplied to the system

ΔW= Work done by the system.

ΔU = Change in the internal energy of the system.

If Q is positive, then there is a net heat transfer into the system, if  W is positive, then there is work done by the system. So positive Q adds energy to the system and positive W takes energy from the system.

It can also be represented as  ΔU=ΔQ-ΔW

We can say that internal energy tends to increase when heat is given to the system and vice versa.

Angular acceleration is defined as the rate at which an object's angular velocity changes over time. It is given by the formula:
Angular acceleration (α) = Change in angular velocity (Δω) / Change in time (Δt)

Shape of equipotential surfaces for a uniform electric field along x-axis are Planes normal to the field.

Beyond the elastic limit, if still some force is applied to the body, at first the body deforms completely and when it can’t deform more, it starts to break into pieces. Now when the plastic range is small, on less extent of applied external force the body would break. And we know such objects are called brittle.

When the car moves in a curvature of radius R, the force acting towards the centre of curvature must be equal to mv²/R 
where m is mass of the car, v is the speed of car
But when we draw the free body diagram of the car the only force towards the centre of curvature is the friction force which is f = μmg
Hence by comparing we get v = √μgR
Substituting values gives, v= 20ms^-1

The use of nuclear weapons would cause the formation of smoke clouds preventing the light from the sun reaching earth surface and it will also deplete the atmosphere and therefore stopping the greenhouse effect and thus doubling the cooling effect.
Hence the correct answer is option C.

Explanation:In order to take a safe turn, the cyclist has to bend a little from his vertical position. In this case, a component of the reaction provides the required centripetal force.If q is angle made by the cyclist with the vertical then

In actual practice, the value of q is slightly less because the force of friction also contributes towards the centripetal force.

Making the mentally retarded students learn through concrete experiences and making them apply the learned skills will surely work for mentally retarded children. Therefore, it becomes important for the teacher to plan out instructions for clear understanding of the concepts. 

The statement "Children actively construct their understanding of the world" was said by Piaget. Piaget saw the kid as constantly creating and re-creating his own model of reality, achieving mental growth by integrating simpler concepts into higher-level concepts at each stage. He argued for a “genetic epistemology,” a timetable established naturally for the event of the child’s ability to think, and he traced four stages therein development. Hence, the correct answer is, 'Piaget.'

The national education policy 2020 is the first education policy of the 21st century and aims to address the many growing development imperatives of our country. This policy progress the revision and revamping of all aspects of the education structure, including its regulation and governance, to create a new system that is aligned with the aspirational goals of 21st-century education and improve the quality of the education system.
Key Points 

The curriculum framework for adult education will include at least five types of programes:-

• foundational literacy and numeracy
• critical life skills (including financial literacy, digital literacy, commercial skills, health care and awareness, child care and education, and family welfare)
• vocational skills development (with a view towards obtaining local employment)
• basic education (including preparatory, middle, and secondary stage equivalency)
• continuing education (including engaging holistic adult education courses in arts, sciences, technology, culture, sports, and recreation, as well as other topics of interest or use to local learners, such as more advanced material on critical life skills).

Thus it is clear that the purpose of new education policy is to improve the quality of the education system.

The correct option is Option 1, i.e., ‘deposited into’.
The correct tense of the bracketed phrase has to be used for the sentence to make proper sense. Therefore, ‘deposit into’ has to be replaced by ‘deposited into’, making Option 1 the correct choice

Filter is to purify something whereas pollute means to make the things dirty. Thus, pollute is the best antonym to filter.
Example- The smoke from old diesel vehicles pollute the air the most.
