Answer:

The start of menstruation is a sign of reproductive maturity.

Step-by-step explanation:

During the monthly hormone cycle the mucous membranes lining the inside of the uterus prepare for the possibility that an egg might be fertilized and settle in the uterus. The mucous membranes supply nutrients to the embryo if the woman gets pregnant. If the egg cell is not fertilized, it dies.
