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. The organ systems responsible for integration and coordination are the nervous and endocrine systems.

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

Correct answer: A

Rationale: The correct answer is True. The nervous and endocrine systems are indeed responsible for integration and coordination in the body. The nervous system uses electrical impulses to send signals quickly, while the endocrine system uses hormones to send chemical messages more slowly. Together, they work to regulate various bodily functions and maintain homeostasis. The other choices are incorrect as the statement accurately describes the roles of the nervous and endocrine systems in integration and coordination.

3. Do chromosomes get longer as a cell ages?

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

Correct answer: B

Rationale: Chromosomes do not get longer as a cell ages. In fact, chromosomes condense and become more compact during cell division to ensure proper segregation. Choice A is incorrect because chromosomes do not elongate with age. Choice C is not the correct answer as there is scientific evidence to support that chromosomes do not lengthen over time. Choice D is not the right option as the correct answer is 'False' in this case.

4. The ability of an organism to sense and react to changes in its body illustrates

• A. circulation.
• B. respiration.
• C. responsiveness.
• D. absorption

Correct answer: C.

Rationale: The correct answer is 'responsiveness.' Responsiveness refers to the ability of an organism to detect and respond to stimuli in its environment. In this context, it specifically relates to an organism's ability to sense and react to changes within its body. Choices A, B, and D are incorrect. Circulation refers to the movement of fluids within an organism, respiration is the process of exchanging gases, and absorption is the uptake of substances by cells or tissues.

5. Metabolism is defined as _____.

• A. the removal of wastes produced by chemical reactions
• B. the breakdown of substances into simpler forms
• C. the taking in of nutrients
• D. all the chemical reactions occurring in an organism that support life

Correct answer: D

Rationale: Metabolism refers to all the chemical reactions that take place within an organism to sustain life, including processes such as breaking down molecules, building new molecules, and energy production. Choice A is incorrect because it describes excretion rather than metabolism. Choice B is incorrect as it specifically refers to the breakdown of substances, not encompassing the entirety of metabolic processes. Choice C is incorrect as it focuses solely on nutrient intake, which is just one aspect of metabolism.
