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.

Which gland would a doctor check if a person didn't react to stressful situations
Inessa05 [86]

Pituitary gland.


When you feel stress, the pituitary gland, at the base of the brain, increases its production of the hormone ACTH. This hormone tells the adrenal glands, found at the top of your kidneys, to increase their production of hormones. These stress hormones help you to concentrate, speed your reaction time, and boost your strength. Your hypothalamus also helps your body respond to stress.

Which pedigree symbol is used to represent a female carrier of a recessive X-linked trait?
xeze [42]
The answer is a half-filled circle. 

In the pedigree charts, squares present males and circles present females. If a female is healthy, the circle is empty (white). If a female is affected with a trait, the circle is filled-in (usually black). However, if a female is a carrier of a disease, which means that one allele is dominant and one is recessive, then the circle is half-filled.
