During the proliferative phase of the uterine cycle, the
a. corpus luteum is forming.
b. functional zone of the endometrium is restored.
c. fertilized ovum implants.
d. old functional layer is sloughed off.
e. endometrium forms glands and spiral arteries

b. functional zone of the endometrium is restored.

Explanation:

Proliferative phase -

This is the very second phase of uterine cycle , in which due to the estrogen , the lining of the uterus grows , or proliferate .

In this phase , the ovarian follicles secretes estrogen and estradiol .

The function of estrogen is to start the formation of the new layer in the uterus called the endometrium .

And this is how , the endometrium is restored in Proliferative phase .

x = -6.5

explanation:

with this editor, you should be careful to put what you mean. 5/(2x - 7) = 3/(4x +14) is the way i will interpret it. cross multiply

5*(4x + 14) = 3*(2x - 7)       remove the brackets

20x + 70 = 6x - 21             add 21 to both sides

20x+ 70+21= 6x                 combine

20x + 91 = 6x                     subtract 20x

20x-20x+91=6x-20x           combine

91 = - 14x

x = - 91/14

x = - 6.5
