If we could eliminate any disease in the North America, what would we pick if we wanted to most reduce the number of Americans living with long-term disability?
multiple sclerosis
Alzheimer's
heart attacks
strokes

i would say the best option to pick would be multiple sclerosis

Explanation:

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.
