The gland located at the top of the kidney is the ________ gland.
Elza [17]

Answer:

adrenal

Explanation:

The adrenal glands are two endocrine glands in the human body. They are located above the kidneys.  Members of the endocrine system, the adrenal glands are very important to the human body because they make hormones essential for their functioning.

These glands are also responsible for the production of hormones that act on the transformation of fat into glucose by the liver. An example of this hormone is glucocorticoid known as cortisol, which also acts on the degradation of triglycerides. These functions are also performed by the region of the adrenal cortex.

The adrenal glands also produce in the adrenal medulla two other important hormones: adrenaline (also known as epinephrine) and norepinephrine (also known as norepinephrine). These two hormones act on psychic and physical reactions generated by strong emotional situations (mainly related to emotional stress).

Muscles help keep blood flowing normally through the body. How do muscles accomplish this task?
bezimeni [28]

Answer:

Option A, by having a constant supply of blood

Explanation:

Blood that flows to the muscles bring oxygen from the atmosphere to the contracting muscles where it gets consumed.  During large muscle exercise, two physiological needs arise – a) high and prolonged muscle blood flow and b) regulation of blood pressure so that there is adequate perfusion of pressure to all organs. In order to meet both the requirements, the blood flow increases so that the vasoligating muscles do not outstrip the cardiac output.

Hence, option A is correct

balu736 [363]
<span>"Genetic drift is more likely to have an impact on small populations."

Genetic drift is changing the frequency in the allelic pool of a population. This phenomenon impacts mainly smaller populations because these populations have only a few copies of the alleles present. If a change in the frequency of the alleles happens then it may cause the disappearance of certain alleles because there are only so many copies.</span>
