1. Is the elbow distal to the wrist?

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

Correct answer: B

Rationale: The correct answer is False. In anatomical terms, 'distal' means farther away from the center of the body or the point of attachment. The elbow is proximal to the wrist because it is closer to the center of the body. Therefore, the statement that the elbow is distal to the wrist is incorrect. Choice A is incorrect because the elbow is not distal to the wrist. Choice C is incorrect as the anatomical relationship between the elbow and wrist can be determined. Choice D is incorrect as there is a definitive answer to this anatomical question.

2. In negative feedback mechanisms, changes away from the normal state

• A. stimulate changes in the same direction
• B. inhibit all body reactions
• C. stimulate changes in the opposite direction
• D. stimulate a reduction in all body requirements

Correct answer: C

Rationale: In negative feedback mechanisms, changes away from the normal state stimulate changes in the opposite direction. This is a fundamental concept in biological systems where the response to a stimulus opposes the initial change, helping to maintain homeostasis. Choice A is incorrect because negative feedback does not stimulate changes in the same direction. Choice B is incorrect because negative feedback does not inhibit all body reactions, but rather specific responses. Choice D is incorrect because negative feedback does not stimulate a reduction in all body requirements, but rather adjusts specific functions to restore balance.

3. What is assimilation?

• A. changing absorbed substances into different chemical forms
• B. breaking down foods into nutrients that the body can absorb
• C. eliminating waste from the body
• D. an increase in body size without a change in overall shape

Correct answer: A

Rationale: Assimilation is the process of changing absorbed substances into different chemical forms. It occurs after nutrients from food are absorbed into the bloodstream and used by the body. Choice B, breaking down foods into nutrients that the body can absorb, refers to the process of digestion rather than assimilation. Choice C, eliminating waste from the body, describes the process of excretion. Choice D, an increase in body size without a change in overall shape, does not accurately define assimilation.

4. Macromolecules are built of?

• A. Monomers
• B. Incorrect
• C. Not Applicable
• D. None of the above

Correct answer: A

Rationale: The correct answer is A: Monomers. Macromolecules are built from smaller subunits called monomers. Monomers join together through chemical reactions to form larger molecules known as macromolecules. Option B is incorrect as it does not provide the accurate information regarding the composition of macromolecules. Option C is not applicable as it does not offer a relevant choice. Option D is incorrect because there is a specific answer related to the composition of macromolecules.

5. The transition from a hunter-gatherer to an agricultural lifestyle greatly changed the types of diseases and injuries that early peoples suffered.

• A. True
• B. False
• C. Not Sure
• D. All of the above

Correct answer: A

Rationale: The correct answer is True. The transition from a hunter-gatherer to an agricultural lifestyle did indeed greatly change the types of diseases and injuries that early peoples suffered. With the shift to agriculture came increased sedentism, population density, and interaction with domesticated animals, leading to the emergence of new diseases and health challenges. Choice B is incorrect because the statement is true based on historical and archaeological evidence. Choice C is incorrect as there is historical data supporting the impact of this transition. Choice D is incorrect as it is not applicable since all options do not hold true in this context.
