Answer to Question 1

Ans: A
As a result of the sex-determining genes on the Y chromosome, testosterone is present in male fetuses and, by weeks 6 to 12, is responsible for the formation of the penis, prostate, and scrotum. The formation of ovaries in the female depends on the absence of this male hormone. After the male sex organs are formed, testosterone levels temporarily rise, causing a permanent sexual organization of the brain that is different than that in females. Testosterone is also elevated during the first 3 months after birth, causing the brain structures and circuits to be fixed for the rest of a boy's life. These structural differences are thought to be the basis of sex differences that are reflected in behavior from birth.

Answer to Question 2

Ans: A, D
According to the DSM-5, subtypes of circadian rhythm disorders include a delayed sleep phase and shift work type. Although jet lag type is a circadian rhythm sleep-wake disorder, it is not included in the DSM-5. Nightmare and sleep terror are separate disorders.
