Answer:

a. To maintain the uterine lining

Explanation:

Progesterone is secreted by the cells of the corpus luteum. During the uterine cycle, it prepares the uterine endometrium for implantation. During the first trimester, progesterone maintains the uterine lining. Higher levels of progesterone inhibit the secretion of GnRH (gonadotropin-releasing hormone). This results in inhibition of the secretions of FSH and LH which in turn are required for the development of follicle and ovulation respectively.

Lower levels of progesterone during pregnancy results in sloughing off of uterine lining and the embryo during menstruation causing abortion.

Answer:

Every organism possesses in its ribosome a protein that is similar to rpl4. This protein has an amino acid sequence that is similar to the sequence of E. coli’s rpl4.

Phylogenetic tree is a diagram which represents the similarities between different organisms and shows their evolutionary histories.

The presence of a similar genetic sequence or amino acid sequence shows that the gene is common in all those organisms. This means that all organisms had a common ancestor through which the gene or amino acid was transferred. The genetic r amino acid sequence remained common in all the different organisms.
