Answer:
The slow rate at which diffusion occurs over large distances.
Explanation:
Circulatory system may be defined as one of the most important system of the body that contains arteries and veins. Two main types of circulatory system are open circulatory system and closed circulatory system.
The blood flow all over the body to each cell with the help of the circulatory system. Arteries carry oxygenated blood and veins carry deoxygenated blood in the body. The circulatory system increases the rate of blood flow as diffusion do not allow the transport at long distances.
Thus, the correct answer is option (c).

As soon as she steps on the glass piece, the receptors present in the skin of her foot sole sense it and send the information to the control center via sensory neurons. The spinal cord commands the muscles of the effector organ (leg) via motor neurons to move to step away from the glass piece.

This is true. The atmosphere gets tighter as you go up.
