Answer:
The correct answer is C the polar head groups of phospholipid,glycolipid and cholesterol face towards the interior of the bilayer.
Explanation:
Plasma membrane contains various lipid molecules such as phospholipid,glycolipid,sphingolipid and cholesterol.The polar head groups of the phospholipid,glycolipid and cholesterol faces the hydrophilic region which is present outside the lipid bilayer and the nonpolar groups faces the hydrophobic region that is present interior of lipid bilayer.

Answer:
Option A, by having a constant supply of blood
Explanation:
Blood that flows to the muscles bring oxygen from the atmosphere to the contracting muscles where it gets consumed. During large muscle exercise, two physiological needs arise – a) high and prolonged muscle blood flow and b) regulation of blood pressure so that there is adequate perfusion of pressure to all organs. In order to meet both the requirements, the blood flow increases so that the vasoligating muscles do not outstrip the cardiac output.
Hence, option A is correct
