Anatomy

1. Which of the following is NOT a function of the nervous system?

Correct answer: C

Rationale: The correct answer is C: 'Producing insulin.' The nervous system is responsible for detecting touch (option A), regulating body temperature (option B), and controlling muscle movement (option D). Insulin production is actually regulated by the endocrine system, specifically the pancreas. Insulin helps regulate blood sugar levels, which is not a function of the nervous system. It is important to differentiate between the roles of the nervous system and the endocrine system in maintaining bodily functions.

2. The hormone responsible for regulating blood sugar levels is produced by the:

Correct answer: C

Rationale: The correct answer is C: Pancreas. The hormone responsible for regulating blood sugar levels is insulin, which is produced by the pancreas. Insulin helps to lower blood sugar levels by allowing cells to take in glucose from the bloodstream. The pituitary gland (A) is known for producing various hormones that regulate other endocrine glands, while the thyroid gland (B) produces hormones that regulate metabolism. The adrenal glands (D) produce hormones such as cortisol and adrenaline, but they are not primarily responsible for regulating blood sugar levels.

3. Look at the following electron configuration: 1s2 2s2 2p6 3s2 3p6. To which group and period does this element belong?

Correct answer: C

Rationale: ) Group 18, Period 3. Count the total electrons (2 + 2 + 6 + 2 + 6 = 18) and observe the completely filled energy levels. This points to a noble gas in Group 18 (Neon) during Period 3.

4. Which property of a substance remains constant regardless of changes in its shape or size?

Correct answer: a

Rationale: Mass is the measure of the amount of matter in an object and remains constant regardless of changes in its shape or size.

5. Which statement BEST summarizes the author's perspective on bioremediation for plastic pollution?

Correct answer: B

Rationale: The passage acknowledges the potential of bioremediation while highlighting the need for further research, indicating a balanced perspective.

6. The main function of the nephrons is to:

Correct answer: B

Rationale: The correct answer is B: 'Filter blood and remove waste products.' Nephrons are the functional units of the kidneys responsible for filtering blood to remove waste products, excess ions, and water, while reabsorbing essential substances like glucose and amino acids. This process forms urine, which is stored in the bladder before being excreted. Options A, C, and D are incorrect because nephrons do not store urine, produce hormones, or directly control blood pressure; although the kidneys do play a role in long-term blood pressure regulation through mechanisms like the renin-angiotensin-aldosterone system.
