1. Which of the following hormones is responsible for regulating metabolism?

• A. Insulin
• B. Thyroxine
• C. Glucagon
• D. Cortisol

Correct answer: B

Rationale: Thyroxine, produced by the thyroid gland, is the hormone responsible for regulating metabolism. It plays a fundamental role in controlling the body's metabolic rate, affecting processes such as energy production and utilization. Thyroxine also influences growth and development in the body. Choice A, Insulin, is involved in regulating blood sugar levels and promoting the storage of glucose. While insulin has an impact on metabolism, it is not primarily responsible for regulating overall metabolic rate. Choice C, Glucagon, acts in opposition to insulin, stimulating the release of glucose from the liver to increase blood sugar levels. Glucagon primarily targets glucose regulation rather than overall metabolism. Choice D, Cortisol, is known as the stress hormone and plays a role in the body's response to stress, regulation of blood pressure, immune function, and anti-inflammatory actions. While cortisol can have some effects on metabolism during stress responses, it is not the primary hormone responsible for regulating overall metabolic rate.

2. Which word is used incorrectly in the following sentence? Jeremiah seemed enthusiastic when we reported on our astonishing success.

• A. seemed
• B. enthusiastic
• C. astonishing
• D. success

Correct answer: B

Rationale: The word 'enthusiastic' is used incorrectly in the sentence. It should be 'enthusiastic' instead of 'enthusiastically' since it is describing Jeremiah's state of being, not an action he performed. Adverbs like 'enthusiastically' are used to modify verbs, not adjectives like 'enthusiastic'. The other choices ('seemed,' 'astonishing,' 'success') are all used appropriately in the sentence and do not need any correction.

3. What is the primary function of the pancreas in digestion?

• A. To absorb nutrients
• B. To secrete digestive enzymes
• C. To produce bile
• D. To store glucose

Correct answer: B

Rationale: The correct answer is B: To secrete digestive enzymes. The pancreas plays a crucial role in digestion by secreting digestive enzymes that break down carbohydrates, fats, and proteins in the small intestine. These enzymes help in the process of breaking down food particles into smaller molecules that can be easily absorbed by the body for nutrients. Choices A, C, and D are incorrect as the primary function of the pancreas is not to absorb nutrients, produce bile, or store glucose in digestion.

4. Change the following percentage to a decimal: 58%

• A. 0.58
• B. 5
• C. 0
• D. 0

Correct answer: A

Rationale: To convert a percentage to a decimal, move the decimal point two places to the left. Therefore, 58% as a decimal is 0.58. Choice B, 5, is incorrect as it does not represent the conversion of a percentage to a decimal. Choices C and D, both 0, are also incorrect as they do not reflect the correct conversion of 58% to a decimal.

5. Select the word that will make the following sentence grammatically correct. Do not be afraid to consult ___________ your peers.

• A. with
• B. from
• C. by
• D. in

Correct answer: A

Rationale: The correct preposition to use in this sentence is 'with.' The sentence should read: 'Do not be afraid to consult with your peers.' In this context, 'with' is the appropriate preposition to indicate collaborating or seeking advice from your peers. The other prepositions ('from,' 'by,' 'in') do not convey the intended meaning of seeking advice or collaborating with your peers in this context.
