1. Is cadaver dissection against the law in the U.S.?

• A. TRUE
• B. FALSE
• C. Not Sure
• D. None of the above

Correct answer: B

Rationale: Cadaver dissection is not against the law in the U.S. In fact, cadaver dissection is a common practice in medical schools and research institutions for educational and research purposes. The correct answer is 'False' because there are specific regulations and ethical guidelines that govern the use of cadavers for dissection. Choice C, 'Not Sure,' is incorrect as the legality of cadaver dissection is a well-established fact. Choice D, 'None of the above,' is also incorrect as one of the provided options is indeed correct.

2. One characteristic that centenarians share is

• A. a high level of exercise throughout life
• B. long-lived relatives
• C. following the Mediterranean diet
• D. never having smoked

Correct answer: D

Rationale: The correct answer is 'never having smoked.' Research suggests that one of the common characteristics among centenarians is that they have never smoked. Smoking is a well-known risk factor for various diseases and can significantly reduce lifespan. Choice A, 'a high level of exercise throughout life,' is not a universal characteristic among centenarians, although exercise can contribute to a healthy lifestyle. Choice B, 'long-lived relatives,' while genetics can play a role in longevity, not all centenarians have long-lived relatives. Choice C, 'following the Mediterranean diet,' is a healthy dietary choice but not a defining characteristic shared by all centenarians.

3. The muscular system is responsible for body movements, maintenance of posture, and production of body heat.

• A. True
• B. False
• C. Not Sure
• D. None of the above

Correct answer: A

Rationale: The correct answer is A: True. The muscular system is indeed responsible for body movements, maintenance of posture, and the production of body heat. Muscles contract and relax to allow movement, help in maintaining an upright posture, and generate heat through muscle activity. Choice B is incorrect because the functions mentioned are accurate. Choice C is incorrect as the functions of the muscular system are well-established. Choice D is incorrect as there is a correct answer among the options.

4. What effect does aldosterone secretion have on electrolyte levels?

• A. Calcium levels are decreased
• B. Sodium levels are increased
• C. Potassium levels are increased
• D. Magnesium levels are decreased

Correct answer: B

Rationale: Aldosterone is a hormone that primarily acts on the kidneys to increase the reabsorption of sodium and water into the bloodstream. As a result, sodium levels are increased. Choices A, C, and D are incorrect. Aldosterone does not significantly affect calcium, potassium, or magnesium levels.

5. Which of the following best describes a blood clot stimulating further clotting?

• A. a positive feedback mechanism.
• B. a negative feedback mechanism.
• C. a process turning itself off.
• D. nervous system communication

Correct answer: A

Rationale: A blood clot stimulating further clotting is an example of a positive feedback mechanism. In positive feedback, the response enhances or amplifies the original stimulus, leading to an increase in the activity. In this case, the formation of a blood clot triggers more clotting activity, creating a cycle of increasing clot formation. Negative feedback mechanisms, on the other hand, work to maintain homeostasis by counteracting changes. Choices B, C, and D are incorrect as they do not accurately describe the situation of a blood clot stimulating further clotting.
