Ok... This is a bit complicated but bear with me. In a female's body Estrogen and Progesterone are two of the major used to maintain the menstruation cycle. Gonadotrophic substances are an entirely different topic with it being the hormones FSH and LH (These hormones are released while an egg is in development in the ovaries). 

Without going into even deeper specifics. Estrogen is used by the body signal to ovulate, as well as thicken the uterine walls... Progesterone is used to maintain the uterine walls "after" the egg is fertilized. What the pill is suppose to do is actually force a premature ovulation, which is why there is estrogen. The Progesterone's job as is maintain the uterine wall's endometrium to a low level and helps keep blood loss from a period at a minimum. 

If you need clarification please feel free to question.

Which statment best summarizes the
wlad13 [49]

Answer:

Two DNA molecules, containing the same genetic code as the original DNA molecule, are produced.

Explanation:

DNA replication is a very important process that must occur in every living cell prior to cellular division. It is the process by which a DNA molecule makes another copy of itself i.e. duplicates itself, to form two identical molecules of DNA.

In the process of DNA replication, the double-stranded molecule first unwinds to form two single strands of DNA. Each DNA strand serves as a template for making another complementary strand of DNA. At the end of replication, each copy of DNA molecule contains one new strand and one old strand. Both copies contain the same genetic code as the original DNA molecule.
