1. Dr. Fox studies the causes of depression. In other words, she looks at factors that play a role in the ________ of depression.

• A. etiology
• B. epidemiology
• C. prevalence
• D. resiliency

Correct answer: A

Rationale: The correct answer is A, 'etiology.' Etiology specifically deals with the causes or origins of diseases like depression. Choice B, 'epidemiology,' focuses on the patterns, causes, and effects of health and disease conditions in defined populations. Choice C, 'prevalence,' refers to the proportion of a population found to have a condition. Choice D, 'resiliency,' relates to the ability to recover from or adjust to challenges.

2. Which neurotransmitter is reduced in both the manic and depressive phases of bipolar disorder?

• A. Acetylcholine
• B. Dopamine
• C. Norepinephrine
• D. Serotonin

Correct answer: D

Rationale: The correct answer is D, Serotonin. Serotonin levels are reduced during both the manic and depressive phases of bipolar disorder. Acetylcholine (choice A) is not typically linked to bipolar disorder. Dopamine (choice B) and norepinephrine (choice C) are more commonly associated with conditions like schizophrenia and depression, respectively, rather than bipolar disorder. Therefore, they are not the neurotransmitters reduced in both manic and depressive phases of bipolar disorder.

3. During which period of psychosexual development does a child become preoccupied with the development of skills and activities?

• A. Genital
• B. Phallic
• C. Latency
• D. Pubertal

Correct answer: C

Rationale: The correct answer is C, Latency. In the Latency stage of psychosexual development, which occurs from around age 6 to puberty, children are focused on developing skills and engaging in activities rather than exploring sexuality. This period is characterized by the suppression of sexual impulses and the emphasis on social and intellectual pursuits. Choice A, Genital, refers to the final stage of psychosexual development in Freud's theory where individuals reach sexual maturity. Choice B, Phallic, pertains to the stage where children become aware of anatomical differences between boys and girls and develop unconscious sexual desires for the opposite-sex parent. Choice D, Pubertal, is not a recognized stage in Freud's psychosexual development theory.

4. What are genes made of?

• A. Trisomes
• B. Chromosomes
• C. DNA
• D. Proteins

Correct answer: C

Rationale: Genes are made of DNA, which is the genetic material that carries the instructions for the development, functioning, growth, and reproduction of organisms. While chromosomes contain genes, they are not what genes themselves are made of. Proteins are involved in gene expression and regulation, but they are not the primary material genes consist of. Trisomes is an incorrect term in this context and does not relate to the composition of genes.

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.
