1. 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.

2. Which of the following characteristics of life and their descriptions are correct?

• A. Responsiveness - detecting and responding to changes in the environment
• B. Assimilation - incorporating absorbed substances into the body
• C. Respiration - obtaining energy from food molecules through oxygen
• D. Circulation - the movement of substances in body fluids

Correct answer: D

Rationale: The correct answer is D: Circulation - the movement of substances in body fluids. Circulation refers to the movement of substances like nutrients, gases, and wastes in body fluids to and from cells. Choice A is incorrect because responsiveness is about detecting and responding to changes in the environment, not obtaining and using oxygen. Choice B is incorrect because assimilation is the process of incorporating absorbed substances into the body, not changing them into chemically different forms. Choice C is incorrect because respiration is the process of obtaining energy from food molecules through oxygen, not the obtaining and using oxygen itself.

3. Which of the following hormones is secreted by the posterior pituitary gland?

• A. Growth hormone
• B. Luteinizing hormone
• C. Adrenocorticotropic hormone
• D. Antidiuretic hormone

Correct answer: D

Rationale: The correct answer is D: Antidiuretic hormone. Antidiuretic hormone (ADH), also known as vasopressin, is produced by the hypothalamus and stored in the posterior pituitary gland. It plays a key role in regulating the body's water balance by controlling the amount of water reabsorbed by the kidneys. Choices A, B, and C are incorrect because Growth hormone is produced by the anterior pituitary gland, Luteinizing hormone is produced by the anterior pituitary gland, and Adrenocorticotropic hormone is produced by the anterior pituitary gland.

4. Is the parietal pericardium attached to the surface of the heart?

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

Correct answer: A

Rationale: The parietal pericardium is a tough, fibrous outer layer that is attached to the diaphragm and the sternum but not directly to the surface of the heart. It forms a sac around the heart known as the pericardial sac. Therefore, the statement that the parietal pericardium is attached to the surface of the heart is false.

5. In all organisms, what is the basic unit of structure and function?

• A. the atom
• B. the molecule
• C. the macromolecule
• D. the cell

Correct answer: D

Rationale: The correct answer is 'the cell.' Cells are considered the basic unit of structure and function in all living organisms. While atoms are the smallest units of matter, they do not represent the basic unit of structure and function in organisms. Molecules are made up of atoms and can vary in size and complexity, but they are not the fundamental unit of life. Macromolecules are large molecules essential for life processes, but they are composed of atoms and do not function as the basic unit of structure and function in organisms. Therefore, the cell, with its organelles and specialized functions, is the correct answer.
