The Himalayas are often referred to as the "Roof of the World" due to their towering peaks and majestic presence. Stretching approximately 2,500 kilometers from the western region of Jammu and Kashmir to the eastern state of Arunachal Pradesh, the Himalayas are the highest mountain range in India and home to iconic peaks like Mount Everest.

Prime numbers between 1 and 30 →13, 17, 19, 23 and 29 (5)
Rest are prime numbers.
Total numbers 12 to 29 = 18
Total composite numbers = 13

Hence, Option A is correct.

According to the information given in the question, we can draw the following diagram.

Thus we can see if a man has to travel to point E from point A  (through these points by the shortest distance), he has to follow a path point A → B → F → E.

Thus travelling from point A, he will pass the first point B.

Hence, the correct answer is "Point B".

Learning disabilities in Mathematics can be assessed most appropriately by the diagnostic test. 
A diagnostic test is a test that is used to measure the level of understanding a student possess regarding any subject area. Teachers conduct diagnostic tests for reading and maths skills and use these results to provide remedial instructions or classes to students as per their level.
Hence, the correct answer is, 'Diagnostic Test.'

If the student is rewarded for his work, he would be stimulated to work in a better way and start showing more interest towards his/her studies.

'Dyslexia' is a term known for reading disorder. The person having this disorder faces difficulty in learning to read or interpret words, letters, and other symbols, but it is not related to general intelligence. It will not have any impact on a person's general intelligence. It is a hereditary disorder that mostly runs in families. Hence, the correct answer is, 'Reading disorder.'

The response of a young child on the basis of the past situation is related to the 'Law of Analogy' of learning. 
The 'Law of Analogy' principle was developed by Edward Thorndike. According to him, an individual makes use of old experiences while learning a new situation. The way young child did he identified the similarities between the past situation and the present one.
Hence, the correct answer is, 'Law of Analogy' of learning.

NEP 2020 emphasizes the role of teachers in promoting critical thinking, creativity, and holistic development of students.

NRED in NEP 2020 aims to establish a centralized repository for educational data to aid research and policymaking.

Motivation is the process of learning that defines a reason for a person to do something or the desire a person has to do something. It creates interest in learning among young learners. If learners are motivated they will perform their work efficiently and effectively and if they are not motivated to do something then it will affect their performance.
Hence, the correct answer is, 'Creates interests for learning among young learners.'

National Education Policy 2020 is the first education policy of the 21st century and aims to address the many growing developmental imperatives of our country.

• This Policy proposes 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 the 21st century.

According to Piaget, language is a symptom of existing cognitive structures of the child. There are four major cognitive stages: sensorimotor, pre-operational, concrete-operational and formal operations. Language acquisition varies depending upon the particular stage of development.
Skinner, and not Bruner, explains "language acquisition is measured in terms of learning principles or more particularly, a child's operant conditioning techniques".

Hearing impairment refers to hearing loss that prevents a person from totally receiving sounds through the ear. If the loss is mild, the person has difficulty hearing faint or distant speech. 

• Hearing is one of the five senses. Most normal-hearing persons do not fully appreciate the significance of the sense of hearing, and often, do not understand the difficulties faced by the hearing impaired.
• People who are born with hearing impairment, do not learn to speak by themselves, as others do but they can easily move from one place to another and take care of themselves.

Key Points

Language and Speech Development Barrier in Children with Hearing Impairment

• Hearing impairment is a great barrier to the normal development of language; the child with such impairment is at a severe disadvantage in virtually all aspects of language development.
• A considerable number of educators of deaf individuals believe that many of the problems of people who are hearing-impaired related to social and intellectual development are primarily due to their deficiencies in language.
• When the child meets other hearing-impaired children and realizes other people face similar challenges and manage fine, regardless of language or level of hearing, it supports identity development and increases confidence.

Additional Information

• For a child with visual impairment, then the teacher has to ensure that besides visual strategies, he/she also explains orally and uses models that the child can explore by tactile sense.

Hence, we can conclude that Hearing-impaired children exhibit barriers to communication by language.

Non-discursive communication refers to any form of communication that does not involve the use of words or language.

• Speaking involves the use of words or language to communicate, which is the opposite of non-discursive communication.
• Non-discursive communication includes forms of communication that do not involve the use of words, such as facial expressions, body language, gestures, and silence.
• It is an important aspect of human communication and can play a significant role in how we interact with others and convey meaning and emotion.

Thus, it is concluded that Speaking is NOT a form of non-discursive communication.

Moral development is one’s ability to take decision about right and wrong.

Moral development is the process through which children develop proper attitudes and behaviors toward other people in society, based on social and cultural norms, rules, and laws.

Deductive Reasoning is also known as deductive logic. It is a process of reasoning that involves moving from one or more statements to a logically certain conclusion or moves from general to particular. For eg- All women are geniuses. Rhea is a woman. Thus, we can conclude that Rhea is a genius. 
Hence, the correct answer is, 'Reasoning from general to particular.'

Trans-2-butene + 6O₂(g) → 4CO₂(g) + 4H₂O(l)
∆H = -647.0 kcal/mol ---(I)
1 - butene + 6O₂(g) → 4CO₂(g) + 4H₂O(l)
ΔH = -649.8 kcal/mol ---(II)
On (I)-(II)
Trans-2-butene → 1 - butene
ΔH = 2.7 kcal/mol
ΔH = (H_f)_1-Butene - (H_f)_{trans-2-butene}
= H₂ - H₁
H₂ - H₁ = 2.7 -----(A)
And 9ΔH₁ + 5ΔH₂ = 0 -----(B)
On solving eqn (A) and (B), we get
H₁ = -1.0 and H₂ = 1.8

More noble metal is cathode and is protected from rusting by active metal which is anode.

Electron transport is not related to light reaction. It is because light reaction is mainly based on photochemical processes like light absorption, water splitting, the formation of ATP and NADPH, etc. where electron transport is not included.

Correct option is A. Cup-shaped

Energy is a fundamental requirement for all living organisms to carry out their various biological processes. Within cells, energy is stored and transferred in different molecules. The molecule that primarily stores and transfers energy in living systems is called adenosine triphosphate, or ATP.

A: FAD (Flavin adenine dinucleotide) is another molecule involved in energy transfer within cells, but it is not the primary molecule for energy storage.

B: NADH (Nicotinamide adenine dinucleotide) is an important molecule in cellular respiration, which is involved in the transfer of electrons and hydrogen ions during energy production. While it plays a role in energy transfer, it is not the primary molecule for energy storage.

D: ADP (Adenosine diphosphate) is the molecule that forms when one phosphate group is removed from ATP. It is the "lower energy" form of ATP and can be converted back into ATP by adding a phosphate group. However, it is not the primary molecule for energy storage.

The crucial events in aerobic respiration are the complete oxidation of pyruvate and the passing on of the electrons removed as a part of the hydrogen atoms to molecular oxygen with the simultaneous synthesis of ATP.

The value of R.Q. depends upon the nature of the respiratory substrate (the organic food matter oxidised in respiration) and its oxidation.

A peptide bond is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water (H₂O). This is a dehydration synthesis reaction (also known as a condensation reaction), and usually occurs between amino acids.

The lipid molecules are amphipathic, i.e., they possess both polar hydrophilic (water loving) and nonpolar hydrophobic (water repelling) ends. The hydrophilic region is in the form of a head occurring at outer surface while the hydrophobic part contains two tails of fatty acids. Hydrophobic tails usually occur towards the centre of the membrane. It results in the formation of a lipid bilayer. Most common lipid in the bilayer is phospholipid.

The plants which grow in dry or xeric conditions or where availability of water is negligible, are known as xerophytes. Opuntia and Asparagus are succulents which store water in their stem and root respectively.

Dinoflagellates are basically unicellular, motile and biflagellate, golden brown, photosynthetic protists. The two flagella are different (heterokont), one transverse flagellum and other longitudinal flagellum.The longitudinal flagellum is narrow, smooth, directed posteriorly and lies in the sulcys. The transverse flagellum is ribbon-like and lies in the cingulum or annulus. The two types of flagella beat in different directions. A well defined nucleus is present, which has been named as mesokaryon.

Synapsis (also called syndesis) is the pairing of two homologous chromosomes that occurs during meiosis. It allows matching-up of homologous pairs prior to their segregation, and possible chromosomal crossover between them. Synapsis takes place during zygotene of Prophase I of Meiosis I. During zygotene stage, synapsis begins with a synaptonemal complex forming between homologous chromosomes. Homologous chromosomes pair up through the process of synapsis to form bivalents.
