Leguminous plant and rhizobium sp is known as

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 : )

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.
