In a healthy person standing at rest, a comparison of arterial blood pressure measured in the arm with that measured in the legs shows that the pressure in the leg is.

a. lower because the blood flow rate is less
b. greater because the column of blood between the arm and leg has hydrostatic pressure
c. same because viscosous pressure loss precisely compansates the hydrostatic pressure increase
d. lower because viscous flow resistance causes pressure loss

b. greater because the column of blood between the arm and leg has hydro-static pressure

Explanation:

The use of the "depth" equation explains it very well.

answer; (d) spontaneous processes are characterized by the overall conversion of order to disorder;

dopamine..

"it was found that some people who were taking the drug l-dopa to raise their levels of dopamine were developing schizophrenic-like symptoms supporting research a strength of the dopamine hypothesis is that there are many studies which have shown support for the neurochemical explanation."
