1. what is the cause for the secretory phase of the uterine endometrium

a) 0 estrogen alone
b) high progesterone relative to estrogen
c) it was the russians!
d) high progesterone alone ; 0 estrogen
e) high estrogen relative to progesterone

Explanation:

1. The DNA - binding domain of nuclear hormone receptors is highly conserved among all nuclear receptors.
2. During the proliferative phase of the uterus, estrogen from the maturing follicle predominates.
3. Endometrial angiogenesis is associated with the proliferative phase of the uterine cycle, which is under the control of estrogen.
4. Oxytocin and ADH (vasopressin) are hormones of the posterior pituitary.
5. Women do not have an infinite number of oocytes, so it is False.
6. FSH and LH receptors are plasma membrane receptors.
7. Ovary numbers are not a factor that likely affects the age of 1st menarche.
8. The secretory phase of the uterine endometrium is caused by high progesterone relative to estrogen.

Answer:

1. b) DNA - binding domain
2. a) estrogen; maturing follicle
3. d) proliferative; estrogen
4. e) oxytocin and ADH (vasopressin)
5. b) False
6. d) plasma membrane receptors
7. a) ovary numbers
8. b) high progesterone relative to estrogen
