7. Which of the following statements are accurate?

A. LH can stimulate Leydig cells to produce testosterone.
B. FSH and LH stimulate the follicle to grow.
C. A surge of LH will trigger ovulation.
D. LH stimulates Sertoli cells to nourish developing sperm
E. LH and Oxytocin are both important in gametogenesis

Option A, B and C.

Explanation:

Leutinizing hormone and follicle stimulating horme are secreted by the gonadotropic cells of the anterior pituitary gland. These hormones stimulate male testes and female ovaries.

The leutinizing hormone stimulate ledyg cells to secrete testosterone and androsterone.

Leydg cells is an interstitial cells that is found in the testes.

Leutinizing hormone and follicle stimulating hormone stimulate follicular growth and ovulation.

When the oestrogen secreted get to a certain stage, it stimulate the pituitary gland to make leutinizing hormone release a surge. When the follicle mature, leutinizing hormone surge trigger ovulation i.e the ripened egg break and it is release through the follicle.

the answer is: trichonympha lives in the gut of termites and digests cellulose eaten by the termite.

this is an example of a symbiotic association of a protozoan with its mode of association.
