- A. allowing muscles to relax after contraction
- B. assisting the operation of hundreds of enzymes
- C. synthesis of protein in the soft tissues
- D. regulation of body temperature
Correct answer: D
Rationale: Magnesium plays a key role in muscle relaxation, enzyme operation, and protein synthesis, but it is not directly involved in regulating body temperature.
2. Which hormone is produced in fat tissue and helps regulate body fat by suppressing appetite?
- A. glucagon
- B. ghrelin
- C. leptin
- D. insulin
Correct answer: C
Rationale: The correct answer is C, leptin. Leptin is a hormone produced by fat cells that helps regulate energy balance by suppressing hunger, thus aiding in the regulation of body fat. Glucagon (choice A) is a hormone that raises blood glucose levels, ghrelin (choice B) stimulates appetite, and insulin (choice D) regulates blood sugar levels and promotes glucose uptake.
3. Do we know all there is to know about the structure and function of the human body?
- A. Yes
- B. No
- C. Not Sure
- D. None of the above
Correct answer: No
Rationale: No, the statement that we know all there is to know about the structure and function of the human body is false. The human body is complex, and there is still much to discover and understand about its intricate functions. Science and medicine continue to make new discoveries and advancements in understanding the human body. Choice A is incorrect because it claims that we know everything, which is not true. Choice C is not the best answer as it implies uncertainty rather than acknowledging the ongoing research and discoveries in this field. Choice D is not the correct option as there is a definitive answer to the question.

- B. Turn off the oxygen when not in use
- C. Avoid open flames or smoking near oxygen
- D. Increase the oxygen flow rate as needed

Choice A is not relevant to oxygen therapy. Choice B is incorrect as oxygen should not be turned off when in use as prescribed. Choice D is incorrect because adjusting the oxygen flow rate without healthcare provider guidance can be dangerous.
