The relationship of blood flow (Q), resistance (R), and pressure (P) in a vessel can be expressed by which equation?
A. Q = P/R.
B. Q = R/P.
C. Q = PQ.
D. P = Q/ R
Answer:
A. Q = P/R.
Explanation:
Resistance is the force that counteracts the blood flow and slows down the speed of the blood flow. It occurs due to friction between blood and the walls of blood vessels. Resistance is regulated by the size of the blood vessels, length of the blood vessels and viscosity. Blood always flows from the region of the higher blood pressure towards the lower one. Therefore, blood flow is directly proportional to pressure and is indirectly proportional to the resistance.
So, Q= P/R

Have a nice day
The answer is, B. Cosmic background radiation is blue-green.
Answer:
The liver stores glucose to power the cells during periods of low blood sugar. Skipping meals and poor nutrition can lower blood sugar. By storing glucose, the liver makes sure that blood glucose levels remain steady between meals and during sleep. When blood glucose falls, cells in the pancreas secrete glucagon.

Multicellular organisms are more complex and it the organism such as a human did not differentiate the cells would not be able to compensate for all the functions that the body has developed through evolution
