Answer:
Are small vessels within the tunica externa of large arteries and veins. (Ans E).
Explanation:
Vasa vasorum: It is defined as a complex system of small blood vessels that helps to provide the larger arteries and veins' walls. It is 3 different types in structure:
1) Internae: It is obtained from the artery lumen and later divide into the vessel wall.
2) Externae: It is obtained from the artery branches.
3) Vasorae: It is obtained within the artery vessel wall then leave into the lumen.
Vasa vasorum helps to provide nourishment which is necessary for growth and supply of blood for tunica media of large vessels and tunica adventitia.

The decrease of human growth hormone is associated with the loss of muscle tissue as we age.
<h3>What is a hormone?</h3>
A hormone is a chemical messenger that is released into the bloodstream in order to carry out particular physiological functions.
The human growth hormone is a hormone required during the growth that induces cell division during specific stages of human development.
The human growth hormone is secreted by specialized cells present in the anterior pituitary gland.
The expression level of the gene encoding the human growth hormone can be used in clinical settings in order to determine the presence of abnormal growth during embryo development.
In conclusion, the decrease of human growth hormone is associated with the loss of muscle tissue as we age.

What do you mean <span>It has been observed that certain species of insects which had not previously caused significant harm have become serious pests. the best explanation for this phenomenon is that the pesticide killed off predators which had previously held this species in check. a mutation occurred in the species. the pesticide increased the vigor of the species. was able to be used by the pest as an additional food source is also a reproductive for some insect species. </span><span />
I believe a cell with membrane-bound proteins that selectively bind a specific hormone is called that's hormone's target cell. Hormones are chemical substances that effect the activity of another part of the body (a target cell). The main function of endocrine glands is to secrete hormones directly into the bloodstream, the hormones serves as messengers, controlling and coordinating activities throughout the body.
