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. 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.

3. Are kidneys part of the lymphatic system?

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

Correct answer: B

Rationale: The correct answer is False. Kidneys are not part of the lymphatic system; they are part of the urinary system. The lymphatic system is a network of tissues and organs that help rid the body of toxins, waste, and other unwanted materials. Therefore, choices A, C, and D are incorrect because kidneys are not associated with the lymphatic system.

4. Which of the following is not true of organelles?

A. They carry out specific activities.
B. They are only present in human cells.
C. They are composed of aggregates of large molecules.
D. They are found in many types of cells.

Correct answer: B

Rationale: Organelles are not exclusive to human cells but are present in various types of cells across different organisms. Option B is incorrect as it suggests that organelles are only found in human cells, which is false. Choices A, C, and D are correct statements about organelles. Organelles indeed carry out specific activities, are made up of aggregates of large molecules, and can be found in many types of cells.

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.
