Chemistry

1. What is the term for the process of breaking a large molecule into smaller fragments by applying heat?

Correct answer: D

Rationale: Pyrolysis is the process of breaking down large molecules into smaller fragments by applying heat. The other choices involve different chemical processes.

2. Nuclear binding energy represents the energy required to:

Correct answer: B

Rationale: Nuclear binding energy is the energy required to hold the protons and neutrons within a nucleus together. This energy is necessary to overcome the electrostatic repulsion between positively charged protons in the nucleus. Option A, separating an electron from its atom, is related to ionization energy, not nuclear binding energy. Option C, causing nuclear fission, involves splitting a heavy nucleus into smaller nuclei, releasing energy but not directly related to the binding energy. Option D, inducing nuclear fusion, involves combining two light nuclei to form a heavier nucleus, also not directly related to the energy required to hold protons and neutrons together within a nucleus.

3. The intricate network of blood vessels responsible for transporting blood throughout the body is the:

Correct answer: B

Rationale: The correct answer is B: Circulatory system. The circulatory system is responsible for transporting blood, oxygen, nutrients, and other substances throughout the body. It consists of the heart, blood vessels (arteries, veins, and capillaries), and blood. The lymphatic system (A) is a separate system that helps to maintain fluid balance in the body and plays a role in the immune response. The nervous system (C) is responsible for transmitting signals between different parts of the body and the brain. The respiratory system (D) is responsible for the exchange of oxygen and carbon dioxide in the body through breathing. In this question, the circulatory system is specifically mentioned as the network of blood vessels responsible for transporting blood, making it the correct answer.

4. Deficiency of which hormone can lead to stunted growth and developmental delays in children?

Correct answer: C

Rationale: The correct answer is C: Growth hormone. Growth hormone plays a crucial role in stimulating growth, cell reproduction, and regeneration in humans. Deficiency of growth hormone can lead to stunted growth and developmental delays in children. Estrogen and testosterone are sex hormones responsible for sexual development and characteristics, but they do not directly impact growth. Insulin is a hormone that regulates blood sugar levels and is not associated with stunted growth or developmental delays.

5. What term describes the bouncing back of waves after striking a surface or boundary?

Correct answer: c

Rationale: Reflection occurs when waves bounce back after hitting a surface or boundary.

6. What is the main function of transition words and phrases in writing?

Correct answer: C

Rationale: Transition words and phrases bridge ideas, create logical flow, and enhance the coherence of your writing.
