4 (3 x2 - 5)3
12 x (3 x2 - 5)4
6 x (3 x2 - 5)3
24 x (3 x2 - 5)3

The decomposition of the corpus luteum in the ovary of a non-pregnant woman at the end of the menstrual cycle results in:
Continued growth of the uterine lining
Secretion of huge amounts of LH
A sharp drop in the concentration of the hormone progesterone leads to the breakdown of the uterine lining, the rupture of its capillaries, and the occurrence of menstruation
Placenta formation
3.

Part of the rRNA molecule that makes up the subunit of the ribosomal subunit
Release factor protein
DNA polymerase enzyme
Helix enzyme
4.
