Answer:
The correct answer is pituitary gland.
Explanation:
The pituitary gland is called the master gland because it regulates the secretion of many other endocrine glands. Pituitary is responsible for the secretion of hormone that regulated the level of estradiol and progesterone during the menstrual cycle.
Anterior pituitary release FSH(follicle-stimulating hormone) and LH(Luteinizing hormone) after it gets stimulation by GnRH secreted by the hypothalamus. FSH help in the production of estrogen by stimulating follicle and LH is responsible for the production of progesterone from corpus luteum. Therefore the correct answer is the pituitary gland.
In a ring species gene flow occurs between neighboring populations of a species, but at the end of the ring populations don’t interbreed.
When plants are allowed to self-fertilize generation after generation, the exact same physical traits appears without any change. Such plants are called pure line or true-breeding. For example, tall plants always produce tall plants and true-breeding dwarf plants always produce dwarf plants on selfing.
