Answer:

5%

Explanation:

The adrenal cortex in both males and females produce a small amount of weak androgens. One of the major weak androgen secreted by adrenal cortex is dehydroepiandrosterone (DHEA).

Levels of dehydroepiandrosterone secretion exhibit changes with age. The dehydroepiandrosterone secretion increases till the age of 20-24 years and falls off with increasing age after the age of 30 years in both males and females. The DHEA production at the age of 80 years is about 5% of its secretion at the age of 30 years.

Lh is released by the anterior pituitary gland to stimulate sertoli cells to produce sperm. (lo 13.2) true or false
harina [27]
This is false for a number of reasons. While LH (which stands for Leutinizing Hormone) is released by the anterior pituitary gland and can be present in both females and males, it play a more predominant role in females. Working closely with FSH (Follicle Stimulating Hormone) a surge in LH begins the process of ovulation and the development of the Corpeus Leuteum.

In Males it is used both for the production of sperm but to stimulate the production of testosterone.

In a particular woodland community, two species of rodents coexist: mice and chipmunks. Both species compete for the same kinds
scZoUnD [109]

Answer:

First, we take the owl out, the total number of mouse increases at a higher rate and the chipmunks are also decreasing in numbers. In an ideal ecosystem, both mice (lets call it "a") and chipmunks (lets call it "b") should increase since the restraining factor has been removed. But that is the opposite of what we should see. In that case, we will take the owl to be the "limiting factor" for the rodents.

Am

The rodents will have free movement and exercise their fitness over the area, competition sets in between the two species. So we see, a flourishes while b dies out. This can be viewed most predictably that a has an overall greater fitness and would easily get resources and strive readily, which influences the survival rate for 2.

Hope you got something in any realm of understanding?
