1. During conception, the 23 unpaired chromosomes in the ovum and sperm combine to form 23 pairs in an entirely new cell called the?

A. Embryo
B. DNA
C. Fetus
D. Zygote

Correct answer: D

Rationale: The correct answer is D, Zygote. A zygote is formed when the 23 chromosomes from the ovum and sperm combine during conception. It is the initial cell formed and marks the beginning of a new organism. Choice A, Embryo, is incorrect as an embryo is formed later in the development process. Choice B, DNA, is incorrect as DNA is the genetic material within the chromosomes but is not the name of the new cell formed after fertilization. Choice C, Fetus, is incorrect as a fetus is the stage of prenatal development that occurs well after the zygote stage.

2. Which of the following explanations for the relationship between SES and abnormal behavior is not supported by the existing data?

A. Low SES may cause abnormal behavior.
B. Abnormal behavior is more likely to go untreated in those of low SES.
C. Recovery from loss of a job may be more difficult for those exhibiting signs of mental illness.
D. High SES may cause abnormal behavior.

Correct answer: D

Rationale: The correct answer is D because high SES as a cause for abnormal behavior is not supported by existing data. Abnormal behavior is often associated with factors like stress, trauma, genetics, or environmental influences. High SES is not a known cause of abnormal behavior. Choices A, B, and C are more plausible explanations: Low SES may lead to limited access to mental health care, untreated abnormal behavior due to financial constraints, and difficulties in coping with mental health issues after job loss, respectively.

3. How do socioeconomic factors affect mental health?

A. Socioeconomic factors do not affect mental health.
B. Socioeconomic factors are one of the primary determinants of mental health.
C. Socioeconomic factors only affect mental health in extreme cases.
D. Socioeconomic factors have no clear impact on mental health.

Correct answer: B

Rationale: The correct answer is B. Socioeconomic factors like income and education levels are key determinants of mental health. They influence access to resources such as healthcare, housing, and social support systems, which can impact an individual's mental well-being. Additionally, socioeconomic factors can contribute to stress levels and overall quality of life, which in turn affect mental health. Choice A is incorrect because socioeconomic factors do play a significant role in mental health outcomes. Choice C is incorrect as socioeconomic factors have a broad impact on mental health beyond extreme cases. Choice D is also incorrect as numerous studies have shown the clear impact of socioeconomic factors on mental health.

4. What role do hormones play in mental health and behavior?

A. Hormones only affect physical processes, not mental health.
B. Hormones play a critical role in regulating mood, behavior, and mental health.
C. Hormones have no effect on behavior.
D. Hormones are only involved in reproductive processes.

Correct answer: B

Rationale: Hormones play a critical role in regulating mood, behavior, and mental health, influencing everything from stress response to emotional stability. Choice A is incorrect because hormones have a significant impact on mental health in addition to physical processes. Choice C is incorrect as hormones do have a notable effect on behavior. Choice D is incorrect as hormones have broad functions beyond just reproductive processes.

5. Cortisol is a hormone that ________.

A. is released by the hypothalamus and travels to the pituitary gland, causing it to respond.
B. the pituitary gland releases to stimulate the adrenal gland.
C. the adrenal gland produces that mobilizes the body to deal with stress.
D. reduces the reuptake of the monoamine neurotransmitters.

Correct answer: C

Rationale: Cortisol is a hormone produced by the adrenal gland that mobilizes the body to deal with stress. Therefore, choice C is the correct answer. Choices A and B are incorrect as they inaccurately describe the origin and function of cortisol. Choice D is also incorrect as it describes the action of a different type of substance, not cortisol.
