1. How do neurotransmitters affect behavior and mental processes?

• A. Neurotransmitters have little effect on behavior.
• B. Neurotransmitters are chemicals that influence mood, thought, and behavior.
• C. Neurotransmitters have a minor role in mental health.
• D. Neurotransmitters determine intelligence levels.

Correct answer: B

Rationale: Neurotransmitters are chemicals that influence mood, thought, and behavior, playing a significant role in mental health. Choice A is incorrect as neurotransmitters do have a notable effect on behavior. Choice C is incorrect as neurotransmitters have a major role in mental health. Choice D is incorrect as neurotransmitters do not solely determine intelligence levels.

2. In an experiment, the investigators manipulate variables to learn how one affects another.?

• A. A data-collection method in which participants respond to questions
• B. The entire group that is of interest to a researcher
• C. A detailed description of a single culture or context
• D. A study that tests a causal hypothesis

Correct answer: D

Rationale: The correct answer is D because in an experimental design, investigators manipulate variables to determine the effect of one on another. This process allows researchers to test causal hypotheses by manipulating one variable while keeping others constant. Choices A, B, and C are incorrect as they do not directly relate to manipulating variables in an experiment.

3. Genes ________.

• A. determine how a person will behave.
• B. cause people to develop mental disorders.
• C. determine what characteristics a person will have.
• D. determine the range of characteristics a person has.

Correct answer: D

Rationale: Genes determine the range of characteristics a person has. This is the correct answer because genes contribute to a variety of traits and characteristics a person may have, influencing physical attributes, predispositions to certain conditions, and more. Choice A is incorrect because behavior is influenced by a combination of genetic and environmental factors. Choice B is incorrect because mental disorders are complex conditions influenced by various factors beyond just genes. Choice C is incorrect because genes do not solely determine all characteristics a person will have, as environmental factors also play a significant role.

4. Skinner would agree with all the following statements except:

• A. All behavior is governed by external consequences.
• B. Individuals have free will.
• C. Organisms tend to repeat responses that lead to positive outcomes.
• D. Organisms tend not to repeat responses that lead to neutral or negative outcomes.

Correct answer: B

Rationale: Skinner's behaviorist perspective emphasized that behavior is influenced by external factors and reinforcement, rather than individual free will. Therefore, Skinner would not agree with the statement that individuals have free will. Choices A, C, and D align with Skinner's beliefs as he believed that behavior is shaped by external consequences, organisms tend to repeat behaviors leading to positive outcomes, and organisms tend to avoid behaviors leading to neutral or negative outcomes.

5. Normal human cells have ________.

• A. twenty-two chromosome pairs and one pair of sex chromosomes.
• B. twenty-one trisomy chromosome pairs, one autosomal pair, and one pair of sex chromosomes.
• C. twenty-one chromosome pairs and two trisomy chromosome pairs.
• D. twenty-three chromosome pairs.

Correct answer: A

Rationale: The correct answer is A. Normal human cells have twenty-two chromosome pairs and one pair of sex chromosomes. This adds up to a total of 46 chromosomes. Choice B is incorrect as it mentions twenty-one trisomy chromosome pairs, which is not a characteristic of normal human cells. Choice C is also incorrect as it states twenty-one chromosome pairs and two trisomy chromosome pairs, which is not accurate for normal human cells. Choice D is incorrect as it mentions twenty-three chromosome pairs, which is not the correct number for normal human cells.
