English Grammar

1. The important decision will be made tomorrow. Which word is the comparative form of the adjective "important"?

Correct answer: C

Rationale: The comparative form of an adjective compares two things.

2. 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.

3. The pH scale is used to indicate the concentration of:

Correct answer: A

Rationale: The pH scale measures the concentration of hydrogen ions in a solution, indicating acidity or basicity.

4. Which nitrogenous bases pair with each other in DNA?

Correct answer: B

Rationale: Rationale: In DNA, nitrogenous bases pair with each other in a specific manner known as complementary base pairing. Adenine (A) always pairs with Thymine (T), and Cytosine (C) always pairs with Guanine (G). This pairing is essential for maintaining the structure and function of DNA. Therefore, option B is the correct answer as it correctly identifies the nitrogenous bases that pair with each other in DNA.

5. 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.

6. Which of the following is an example of an unsaturated fatty acid?

Correct answer: C

Rationale: Oleic acid is an unsaturated fatty acid, containing at least one double bond in its hydrocarbon chain. The other choices are saturated fatty acids.
