1. Select the word that means 'a violent seizure.'

• A. revelation
• B. nutrient
• C. contraption
• D. paroxysm

Correct answer: D

Rationale: 'Paroxysm' is the correct answer as it refers to a sudden, violent seizure or outburst. The other choices are incorrect because 'revelation' means a surprising and previously unknown fact, 'nutrient' refers to a substance that provides nourishment, and 'contraption' means a machine or device that is strange or unnecessarily complicated.

2. What is the function of water in photosynthesis?

• A. Combine with carbon dioxide
• B. Absorb light energy
• C. Supply electrons in the light reactions
• D. Transport hydrogen ions in the dark reactions

Correct answer: C

Rationale: The correct answer is C: 'Supply electrons in the light reactions.' In photosynthesis, water is split during the light reactions of photosynthesis, releasing electrons that are used in the formation of ATP and NADPH, crucial for the synthesis of glucose. Choice A is incorrect because water does not combine with carbon dioxide in photosynthesis. Choice B is incorrect as water does not absorb light energy directly. Choice D is incorrect because the transportation of hydrogen ions mainly occurs in the electron transport chain, which is part of the light reactions, not the dark reactions.

3. What is the function of the pituitary gland?

• A. Regulating metabolism
• B. Producing bile
• C. Filtering blood
• D. Controlling muscle movement

Correct answer: A

Rationale: The pituitary gland, known as the 'master gland,' plays a crucial role in regulating various physiological processes by secreting hormones that control other endocrine glands. This includes the regulation of metabolism, growth, reproduction, stress response, and more. Therefore, the correct function of the pituitary gland is regulating metabolism, making choice A the correct answer. Choices B, C, and D are incorrect as the pituitary gland is not involved in producing bile, filtering blood, or controlling muscle movement.

4. Which type of muscle is found in the walls of hollow organs?

• A. Skeletal muscle
• B. Cardiac muscle
• C. Smooth muscle
• D. Striated muscle

Correct answer: C

Rationale: Smooth muscle tissue is found in the walls of hollow organs, such as the intestines, blood vessels, and bladder. It contracts involuntarily, allowing for movements like peristalsis in the intestines and regulation of blood flow in blood vessels. Skeletal muscle (Choice A) is attached to bones and helps in voluntary movements. Cardiac muscle (Choice B) is found in the heart and contracts involuntarily to pump blood. Striated muscle (Choice D) refers to both skeletal and cardiac muscles, which have a striped appearance due to the organization of their filaments. However, smooth muscle (Choice C) is specifically the type found in hollow organs.

5. What is the value of x in the ratio and proportion 0.1:10=x:400?

• A. 5
• B. 4
• C. 50
• D. 25

Correct answer: B

Rationale: To solve the proportion 0.1:10=x:400, first, simplify the left side to 1:100. Then, set up the proportion as 1:100=x:400. Cross multiply to get x = 4. Therefore, the correct answer is B. Choice A (5) is incorrect because it does not match the calculated value of x. Choice C (50) is incorrect as it is not the result of solving the proportion provided. Choice D (25) is incorrect as it does not align with the correct calculation of x.
