Answer 1

During the premenstrual phase of the uterine cycle (menstrual cycle) there is cell division and rebuilding of the endometrium. - True

Rebuilding of the endometrium takes place in Proliferative phase in premenstrual phase of the menstrual cycle.

From the end of the period until ovulation, the uterus builds up a thick inner lining. While the ovaries are working on developing the egg-containing follicles, the uterus is responding to the estrogen produced by the follicles, rebuilding the lining that was just shed during the last period. This is called the proliferative phase because the endometrium (the lining of the uterus) becomes thicker. The endometrium is thinnest during the period, and thickens throughout this phase until ovulation occurs. The uterus does this to create a place where a potential fertilized egg can implant and grow.
