1. What is the function of the adrenal glands?

• A. To regulate metabolism
• B. To produce bile
• C. To produce red blood cells
• D. To regulate blood glucose

Correct answer: D

Rationale: The correct answer is D: To regulate blood glucose. The adrenal glands play a crucial role in regulating blood glucose levels and the body's response to stress. Choice A, 'To regulate metabolism,' is incorrect as the primary role of the adrenal glands is not directly related to metabolism regulation. Choice B, 'To produce bile,' is incorrect because bile is produced by the liver, not the adrenal glands. Choice C, 'To produce red blood cells,' is also incorrect as the production of red blood cells primarily occurs in the bone marrow, not the adrenal glands.

2. What is it called when base units are combined, such as g/mL for density?

• A. combined units
• B. derived units
• C. base units
• D. calculated units

Correct answer: B

Rationale: The correct answer is B: derived units. When base units (such as grams or milliliters) are combined, as seen in g/mL (grams per milliliter) for density, they form derived units. Derived units measure complex quantities that are derived from combinations of base units. Choice A, 'combined units,' is incorrect as it does not specifically refer to the formation of new units from base units. Choice C, 'base units,' is incorrect because base units are the fundamental units from which all other units are derived, not the combinations of units. Choice D, 'calculated units,' is incorrect as it does not accurately describe the concept of combining base units to form a new unit like g/mL for density.

3. What are the primary processes involved in breathing?

• A. Inspiration and Expiration
• B. Inhalation and Exhalation
• C. Respiration and Circulation
• D. Inspiration and Respiration

Correct answer: A

Rationale: The primary processes involved in breathing are inspiration (inhaling air) and expiration (exhaling air). Inspiration is the process of taking air into the lungs, while expiration is the process of expelling air from the lungs. These two phases are crucial for gas exchange, where oxygen is taken in during inspiration and carbon dioxide is expelled during expiration. Choices B, C, and D are incorrect as they either combine inspiration with respiration or include unrelated processes like respiration and circulation. Therefore, the correct pair of processes involved in breathing is A, inspiration and expiration.

4. Janine was so nervous that she was surprisingly graceless and awkward on stage. What is the meaning of the word 'graceless' as used in the sentence below?

• A. Against fear
• B. Without religion
• C. Lacking elegance
• D. Full of caution

Correct answer: C

Rationale: The word 'graceless' in this context means lacking elegance or poise. Janine's nervousness caused her to act awkwardly and without the elegance one would typically expect on stage. Choices A, B, and D are incorrect. 'Against fear,' 'Without religion,' and 'Full of caution' do not accurately capture the meaning of 'graceless' in the given sentence.

5. Which of these examples shows incorrect use of subject-verb agreement?

• A. Neither of the cars is parked on the street.
• B. Both of my kids are going to camp this summer.
• C. Any of your friends are welcome to join us on the trip in November.
• D. Each of the clothing options is appropriate for the job interview.

Correct answer: A

Rationale: The sentence 'Neither of the cars is parked on the street' is incorrect in terms of subject-verb agreement. The subject 'Neither' is singular, so the verb should also be singular, which should be 'is' instead of 'are.' The correct sentence should be 'Neither of the cars is parked on the street.' Choices B, C, and D demonstrate correct subject-verb agreement. In choice B, 'Both' is plural and agrees with the plural verb 'are.' In choice C, 'Any' is singular and agrees with the singular verb 'are.' In choice D, 'Each' is singular and agrees with the singular verb 'is.'
