Answer 1

Ans:

a.Involves the shedding of the endometrium

Explanation: Menstruation (period) is the normal vaginal bleeding of womans monthly cycle. It occurs when the lining of the uterus or endometrium is shed and  pregnancy doesn't occur. During menstruation cycle, the level of Luteinizing hormone and follicle-stimulating hormone are increased but the levels of estrogen and progesterone drops. The ovulation takes place in the midway through menstruation cycle after the follicular phase. HcG hormone produces during pregnancy.
