Answer:
As blood enters the artery, the walls of these vessels expand and contract, which can be felt as the pulse where the arteries run close to the body surface. As blood enters the artery, the walls of these vessels expand and contract, which can be felt as the pulse where the arteries run close to the body surface. It is common to detect the pulse with a few fingers placed on the radial artery on the wrist, or the carotid artery in the neck. Because the walls of the arteries pulse whenever the left ventricle contracts, the pulse rate generally indicates the cardiac function, which is normally between 50 and 85 in a healthy adult.

What does the problem says
Answer:
7) the environment is hypotonic because it is less concentrated than the inside of the cell
8.)the mass would decrease because the stuff inside the cell (which is more concentrated in comparison) would diffuse across the cell membrane into the environment in order to maintain equilibrium
9.) Diffusion in order to maintain equilibrium (moving things across a barrier from a more concentrated area to a less concentrated area in order to have an equal concentration on each side) does not require energy. However, moving matter out of the cell in Diagram C would require energy because it involves moving mass from a less concentrated area to a more concentrated area.
