Answer 2

Ovulation

step by step explanation:

1. a) 444 ova are likely to release from her ovaries. one ova is released during each menstrual cycle. The woman ovulated from 13 to 50, her fertility period was of 37 years. If we consider ovulation in every month the total ova released will be 444.  b) All of the ova are likely to get fertilized.

1. a) It is unlikely for a fertilization to occur two days before ovulation. The progesterone and estrogen levels are high before the process of ovulation begins. Increase in progesterone and estrogen disturbs (endometrial shedding) the endometrium and fertilization cannot occur.   b) After 2 days the possibility is of likely to get fertilized after ovulation as the level of Folicular stimulating hormone is high. Which creates suitable endometrium for fertilization to occur.
