Chemistry

1. Which of the following functional groups is present in carboxylic acids?

Correct answer: C

Rationale: Carboxylic acids contain the carboxyl functional group (-COOH). The other choices are associated with different functional groups.

2. Which of Mendel's Laws states that alleles for a gene segregate during gamete formation?

Correct answer: B

Rationale: Rationale: The Law of Segregation, proposed by Gregor Mendel, states that alleles for a gene segregate during gamete formation. This means that each parent passes on only one allele for each gene to their offspring. This law explains how genetic diversity is maintained and how different combinations of alleles are generated in offspring. The Law of Independent Assortment (option A) states that alleles of different genes assort independently of each other during gamete formation. The Law of Dominance (option C) states that one allele can be dominant over another allele, affecting the phenotype. The Law of Probability (option D) is a general concept that describes the likelihood of a particular event occurring.

3. What is the process by which lighter nuclei fuse to form heavier nuclei, releasing a large amount of energy?

Correct answer: B

Rationale: Fusion is the process by which lighter nuclei combine to form heavier nuclei, releasing a large amount of energy in the process. This process is the source of energy in stars, including our Sun, and is different from fission, which involves the splitting of heavier nuclei into lighter nuclei. Radioactivity refers to the emission of particles or radiation from the nucleus of an unstable atom, while a chain reaction is a self-sustaining reaction where the products of one reaction cause further reactions.

4. The study of fungi is known as:

Correct answer: B

Rationale: Rationale: A) Virology is the study of viruses, not fungi. B) Mycology is the branch of biology that deals with the study of fungi. Fungi are a separate kingdom of organisms that include yeasts, molds, and mushrooms. C) Bacteriology is the study of bacteria, not fungi. D) Parasitology is the study of parasites, which can include various organisms such as protozoa, helminths, and some fungi, but it is not specifically focused on fungi.

5. Regular exercise is beneficial for the muscular system by:

Correct answer: B

Rationale: The correct answer is B: 'Improving muscle strength and endurance.' Regular exercise is beneficial for the muscular system as it helps to strengthen muscles and increase endurance. By engaging in consistent physical activity, muscles adapt and grow stronger, which can enhance overall physical performance and reduce the risk of injury. Exercise also improves blood flow to the muscles, aiding in their recovery and growth. It does not decrease muscle mass (A), make muscles less flexible (C), or increase the risk of muscle tears (D), as long as proper form and gradual progression are followed.

6. Describe the concept of inertia in terms of Newton's first law.

Correct answer: c

Rationale: Inertia refers to an object's tendency to maintain its current state of motion (either at rest or in motion) unless acted upon by an external force.
