Dear student

Please refer the solution below for the said query

a) A = Estrogen and B = Progesterone
b) Ovaries
c) The A peaks before B because the release of gonadotropins (LH and FSH) increases during follicular phase. This causes follicular growth and the growing follicles produce oestrogen.
d) 
Functions of oestrogen:

• Growth and functioning of the female secondary sex organs
• Development of growing follicles and mammary glands
• Regulates female secondary sex characters (Examples − high pitch voice)
•  
• Functions of progesterone:
• Preparing the uterus for implantation
• Acts on mammary glands and stimulates formation of alveoli-like structures storing milk

e) In case implantation occurs, the levels of progesterone continues to be high.


Hope this information clears your doubt about the topic.
