1. The transition from a hunter-gatherer to an agricultural lifestyle greatly changed the types of diseases and injuries that early peoples suffered.

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 is not true of organelles?

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.

3. Homeostasis exists if concentrations of water, nutrients, and oxygen in the body and heat and pressure __________.

Correct answer: B

Rationale: Homeostasis is the body's ability to maintain stable internal conditions despite external changes. To achieve this balance, concentrations of essential substances must remain within specific ranges. Choice A is incorrect because decreasing concentrations would not maintain stability. Choice C is incorrect as increasing concentrations when the body is stressed would disrupt homeostasis. Choice D is incorrect as fluctuating greatly between high and low values would also not support the body's stability. Therefore, the correct answer is B, as it aligns with the concept of homeostasis by emphasizing the need for stability within certain limits.

4. Specialized cell types organized in a way that provides a specific function form

Correct answer: A

Rationale: The correct answer is 'tissues, which build organs.' Specialized cell types organize to form tissues, which in turn build organs. Tissues are groups of cells that work together to perform a specific function. Option B is incorrect because organs are composed of tissues, not the other way around. Option C is incorrect as organ systems consist of multiple organs working together, not building tissues. Option D is incorrect as atoms are the basic building blocks of matter and are not directly involved in forming tissues.

5. Is a cell the basic unit of structure and function of an organism?

Correct answer: A

Rationale: The correct answer is A: True. A cell is indeed the basic unit of structure and function of an organism. Cells are the smallest independently functioning unit in the structure of an organism and carry out vital functions necessary for life. Choice B, False, is incorrect because cells are universally recognized as the fundamental unit of life. Choice C, Not Sure, is incorrect as the role of a cell as the basic unit of an organism's structure and function is a well-established scientific fact. Choice D, None of the above, is incorrect as the statement provided in the question is true.
