If plaque buildup reduces the radius of the artery by a factor of 2, the flow rate becomes 1/16th of the original.
Coronary heart disease results from a deposition of plaque in the blood vessels which transport blood to the heart. When the flow of blood to the heart is hampered or obstructed, the heart can be harmed due to a deficiency of oxygen.
Moreover, if a large section of plaque that is deposited gets displaced from an artery wall, it can get stick in other arteries in the body as well, including those present in the brain.
For convenience, an assumption can be made that the artery is cylindrical in shape with a radius of R. The flow rate of a viscous fluid (blood in this case) is determined by Poiseuille's Law, i.e. Q = (π/8) (ΔP/ηl)r4.

Answer:
green or greenish brown
Explanation:
it has strong, long back legs with webbed feet.the back and sides may be plain or may have dark spots. The arms and legs are spotted or barred with dark. Underparts are white, distinctly or obscurely spotted and mottled.
Answer:
S phase
Explanation:
The S is short for synthesis, which means that DNA is being replicated. This is one of the stages of interphase, when the cell is growing and getting ready to divide. Well, this is the getting ready to divide part of interphase; the cell needs to duplicate its DNA so it has enough to divide out to daughter cells.
