Which describes one effect of the sea level change that occurred during the last ice age?

1

Explanation:

Mostly because it was the BIGGEST thing that really happend during said event. The others happend yes but not as majorly as number 1.

i think the answer is b.

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.

i hope this : )
