Answer to Question 1

Answer: Birth elicits maternal behaviors (grooming, cleaning, consumption of the placenta), which may reflect birth canal distention, as well as the stimuli associated with the pups
(olfactory, auditory cues). The latter alone will elicit maternal behavior in a virgin rodent. Hormones affect maternal behavior but do not organize these (males will show such behaviors, and maternal behaviors occur in virgin mice).

Answer to Question 2

Answer: Twin studies provide powerful evidence for a biological basis for homosexuality with identical twins showing higher concordance values than do fraternal twins, and this effect is noted as well for female homosexuals. A second line of evidence is that androgenization may play a role in that women with congenital adrenal hyperplasia show increased rates of homosexuality/bisexuality. Additional support comes from studies in which childhood experiences were not related to homosexuality.

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.
