Answer:
The answer to the question: velocity of blood is relatively constant as blood flows from the aorta towards the capillaries, would be, B: False.
Explanation:
One way to figure this one out is knowing that the velocity of the blood as it flows through the aorta, comes from the pumping strength of the heart. However, as the blood starts traversing the length of the different arteries, arterioles, and finally reached the capillaries, it encounter two things; first, the speed with which it was originally launched by the heart into the aorta, has already diminished as it moves away from the heart. Second, blood will encounter a series of barriers, not the least of which is resistance from the blood vessels themselves, that will lower the speed with which it will reach the capillares. And this is just as well, as capillaries are much more fragile than arteries themselves, their purpose actually being to serve as exchange points between the cardiovascular system and the different tissues of the body. Their structure is much thinner, and thus needs less speed, in order for exchanges to take place. This is why it is false.
When you shine a light into one pupil, the normal reaction of the other pupil should be to become smaller.
Penlight
The most popular tool for measuring pupil diameter now has a light source and is a penlight. One pupil contracts in reaction to light, whereas the other either doesn't contract at all or contracts more slowly.
Use a penlight to get the maximum amount of pupil contraction in one eye, then quickly move to the other eye and return to the first. A consensual reaction normally causes the second eye to respond with the same pupillary constriction as the first.
Penlight is a useful examination tool for doctors, particularly for small body parts like the mouth, nose, ears, and eyes. They frequently employ it for the pupil test, a physical examination technique used to determine whether pupils contract or remain dilated in response to light.

Answer:
The answer is Progesterone.
Explanation:
The hormone that allows pregnancy to remain in place is Progesterone. It is produced in the ovaries and in the placenta. Progesterone stimulates the growth of the endometrium by preparing it for implanting the fertilized egg. Also this hormone, will act preparing the breasts for the formation of breast milk.
