1. Men with even tiny amounts of dioxin in their bloodstream father __________.

• A. nearly twice as many girls as boys
• B. nearly three times as many boys as girls
• C. more twins and triplets than unaffected men
• D. fewer children than unaffected men

Correct answer: A

Rationale: Men with even tiny amounts of dioxin in their bloodstream father nearly twice as many girls as boys. This is due to the impact of dioxin exposure on sperm cells, leading to a skewed ratio of female to male offspring. Choice B is incorrect as the question specifically mentions that men father more girls than boys. Choice C is incorrect as dioxin exposure does not necessarily lead to more twins and triplets. Choice D is incorrect as men with dioxin in their bloodstream father more girls, not fewer children overall.

2. __________ increases tenfold from the twentieth week until birth.

• A. Amniotic fluid
• B. Brain weight
• C. Fetal length
• D. Neuron production

Correct answer: B

Rationale: Brain weight increases tenfold from the twentieth week until birth. This rapid growth and development of the brain during the prenatal period is crucial for setting the foundation for future cognitive and neurological functions. Choices A, C, and D are incorrect because although they also undergo changes during prenatal development, none of them increase tenfold from the twentieth week until birth, unlike brain weight.

3. To avoid exposure to toxoplasmosis, Kaye should ask other family members to __________.

• A. stop smoking
• B. pick up after the dog
• C. change the litter box
• D. feed the fish

Correct answer: C

Rationale: To avoid exposure to toxoplasmosis, Kaye should ask other family members to change the litter box. Toxoplasmosis is a parasitic infection that can be transmitted through cat feces, so it is important for pregnant women to avoid handling cat litter to reduce the risk of infection. Choices A, B, and D are incorrect because they are not directly related to preventing toxoplasmosis. Smoking cessation is important for overall health but not specifically to prevent toxoplasmosis. Picking up after the dog and feeding the fish are not relevant to preventing toxoplasmosis, as the infection is primarily associated with cat feces.

4. Sigmund Freud constructed his psychosexual theory __________.

• A. on the basis of his adult patients' memories of painful childhood events
• B. by conducting studies of animal behavior
• C. on the basis of interviews with institutionalized children and adolescents
• D. by carefully observing his own children

Correct answer: A

Rationale: Sigmund Freud constructed his psychosexual theory on the basis of his adult patients' memories of painful childhood events. Freud believed that events in early childhood had a significant impact on an individual's development and personality. He used his patients' recollections of childhood experiences to develop his theories on psychosexual development. Choice B is incorrect as Freud did not base his theory on studies of animal behavior. Choice C is incorrect as Freud's theory was not solely based on interviews with institutionalized children and adolescents. Choice D is incorrect as Freud did not construct his theory by observing his own children.

5. What is the function of the corpus luteum?

• A. is where fertilization usually takes place
• B. secretes hormones that prepare the lining of the uterus to receive a fertilized ovum
• C. is one of two long, thin structures that lead to the hollow, softly lined uterus
• D. is one of two walnut-sized organs located deep inside a woman's abdomen

Correct answer: B

Rationale: The correct answer is B. The corpus luteum is a temporary endocrine structure in the ovary that forms after ovulation. It secretes hormones, particularly progesterone, which help prepare the uterine lining for possible implantation of a fertilized ovum. This process is crucial for maintaining a potential pregnancy. Choices A, C, and D are incorrect. Choice A is inaccurate as fertilization typically occurs in the fallopian tubes. Choice C describes the fallopian tubes, not the corpus luteum. Choice D refers to the ovaries, not specifically the corpus luteum.
