1. In the early days, healers transitioned from superstition and magic to using natural chemicals in the field of medicine.

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

Correct answer: A

Rationale: The statement is true. The field of medicine evolved as early healers moved away from superstition and magic, instead focusing on natural chemicals to treat illnesses. This transition marked a shift towards a more scientific and evidence-based approach to healthcare. This historical transition is well-documented in the evolution of medicine. Choice B is incorrect because the statement accurately reflects the historical development of medicine. Choice C is incorrect as the historical transition from superstition to natural chemicals is a well-documented aspect of the evolution of medicine. Choice D is incorrect as the statement provided is true.

2. Do patterns of growth in preserved bones and tooth decay reflect the health of the people they were a part of?

• A. Yes
• B. No
• C. Not enough information to determine
• D. Not applicable

Correct answer: A

Rationale: Patterns of growth in preserved bones and tooth decay can indeed reflect the health of the individuals they belonged to. Growth patterns can indicate malnutrition or diseases during childhood, while tooth decay can signify dietary habits and overall health. Therefore, the correct answer is 'Yes.' 'No' is incorrect because these factors can provide valuable information about the health of individuals. 'Not enough information to determine' is incorrect as these indicators are commonly used in anthropological and archaeological studies to understand health conditions in past populations. 'Not applicable' is also incorrect as the information from bones and tooth decay is relevant to assessing the health of individuals.

3. What causes wrinkled and sagging skin?

• A. Drinking too much water
• B. Heredity alone
• C. Loss of subcutaneous fat and reduced levels of elastin and collagen
• D. Excess subcutaneous fat

Correct answer: C

Rationale: Wrinkled and sagging skin is primarily caused by the loss of subcutaneous fat and reduced levels of elastin and collagen in the skin. Choice A is incorrect as drinking too much water does not lead to wrinkled and sagging skin. Choice B is incorrect because heredity alone does not cause this condition. Excess subcutaneous fat, as mentioned in Choice D, can contribute to a different skin appearance, such as puffiness, but not wrinkled and sagging skin.

4. Signs of aging at the cellular level are

• A. graying hair, waning strength, and wrinkles.
• B. unrepaired DNA and abnormal proteins.
• C. impaired cell division and the ability to break down and recycle worn cell parts.
• D. a fatty liver and clogged blood vessels.

Correct answer: C

Rationale: The correct answer is 'impaired cell division and the ability to break down and recycle worn cell parts.' Aging at the cellular level involves reduced efficiency in cell division and the breakdown/recycling of cellular components, leading to functional decline. Choices A, B, and D are incorrect because they involve external physical manifestations or organ-specific issues rather than cellular-level changes associated with aging.

5. 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.
