Answer to Question 1

b

Answer to Question 2

Primary sex characteristics include the maturation of organs that are directly involved in reproduction (e.g., boys = testes, penis; girls =ovaries, vagina, uterus). For females, menarche (the onset of menstruation) is a key event. For males, spermarche (the first spontaneous ejaculation of sperm-laden fluid) is a key event. Secondary sex characteristics are signs of maturation that are not directly linked to reproductive organs (e.g., boys = facial hair, voice change, girls = widening hips and developing breasts).
