Why might a cell NOT need to duplicate? (select all of that apply) 1. That cell is no longer needed in the body
2.it is unhealthy
3. it is efficient at its job
4.the tissue it is a part of does not need growth or replacement

is this for the e2020 class

i think the answer would be d

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 : )
