1. Absorption is the ability to exhale carbon dioxide.

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

Correct answer: B

Rationale: Absorption is the process of taking in substances such as nutrients or gases. Exhaling carbon dioxide is a part of the process of respiration, not absorption. Therefore, the statement that absorption is the ability to exhale carbon dioxide is false. Choice A is incorrect because absorption does not involve exhaling carbon dioxide. Choice C is incorrect as the concept of absorption can be clearly defined. Choice D is also incorrect as there is a definitive answer to the statement provided.

2. The recent discovery of taste receptors that detect sweetness in the small intestine illustrates that

• A. chemical responses occur in various parts of the body.
• B. new discoveries about anatomy and physiology are still being made.
• C. everything about anatomy and physiology has been discovered.
• D. the molecular and cellular level is crucial in anatomy and physiology.

Correct answer: B

Rationale: The recent discovery of taste receptors in the small intestine illustrates that new discoveries about anatomy and physiology are still being made. This finding demonstrates that our understanding of the human body is continuously evolving. Choice A is incorrect because the discovery does not imply that chemical responses occur in only one part of the body but rather showcases a specific new discovery. Choice C is incorrect as it is highly improbable that everything about anatomy and physiology has been discovered given the complexity of the human body. Choice D is incorrect as while the molecular and cellular level is important in anatomy and physiology, the primary focus of this discovery is on the new findings about the taste receptors in the small intestine.

3. When does cell death first occur?

• A. At age 60.
• B. At age 50.
• C. At puberty.
• D. In the fetus.

Correct answer: D

Rationale: Cell death, also known as apoptosis, first occurs during fetal development when specific cells are programmed to die. This process is essential for shaping and organizing tissues and organs. Choices A, B, and C are incorrect because cell death begins much earlier, during fetal development, rather than later in life or at puberty. Understanding the timing of cell death in different stages of life is crucial in developmental biology.

4. 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: B

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.

5. Is oxygen the primary raw material for new living material?

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

Correct answer: B

Rationale: While oxygen is essential for many living organisms, it is not the primary raw material for new living material. The primary raw materials for new living material are carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur, collectively known as CHNOPS elements. These elements are the building blocks of biological molecules and are essential for life. Therefore, the correct answer is False. Choices C and D are incorrect because the primary raw materials for new living material are well-established in biology.
