How do many of the mammals that inhabit deciduous forests deal with the conditions of the winter season?

they migrate to warmer areas.
they forage or hunt at night.
they develop symbiotic relationships.
they hibernate or stockpile food.

D.) They hibernate or stockpile food.

Explanation:

This question can be confusing for some, so I'll go through the process of elimination to make it easier for everyone. Option A is definitely not correct; only birds migrate to warmer areas. Option B is incorrect because depending on the location of where the mammal is, they can possibly freeze and there won't be enough food to survive. Option C makes no sense; yes, animals can benefit from one another in a symbiotic relationship, but that's not going to keep them warm or alive.

Hope this helps :)

it will increase due to the time span

"menstrual cycle is a complex cycle that consists of several processes. order of occurrence of steps in menstrual cycle are as follows:

1. high progesterone levels maintain the endometrium lining of the uterus.

2. endometrium lining breaks down and low levels of estrogen stimulate the pituitary to release fsh and lh.

3. fsh and lh stimulates the follicles to develop and the oocyte to produce estrogen.

4. rising estrogen levels suppress fsh production and development of other follicles.

5. a spike in lh causes follicle to rupture.

6. a breakdown of corpus luteum causes progesterone level to drop."
