The follicular phase
a. is where the body prepares for pregnancy
b. is when the egg reaches maturation and is ovulated
c. ends with the rise of estrogen and lh levels
d. b and c
e. a, b and c

The correct answer will be option-E.

Explanation:

The menstruation period in females is divided into the follicular phase and the luteal phase.

The follicular phase is characterized by the folliculogenesis or the formation and maturation of the follicles to produce ovum or egg cell. The follicular phase is co-related with the ovulatory phase during the first 14 days of the cycle.

As the follicles matures, the follicle starts releasing estrogens and progesterone as the well rising level of FSH and LH. The rise in LH helps in ovulation while the rise in progesterone maintains the endometrium of uterus to ensure pregnancy.

Thus, option-E is the correct answer.

in 1859, charles darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. he defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".
