The cholesterol increases the stability of the cell membrane
Explanation:
The cholesterol molecules are intercalated in the fatty acid chains of the hydrophobic layer of the bilipid layer. They prevent the fatty acid chains from tightly packing together (from the many hydrogen bond interactions between the chains). Therefore the cell membrane retains fluidity even when temperature go below homeostatic levels in the body. In addition increase the boiling point of the cell membrane (acting the way impurities do) hence reducing its disruption even when temperature goes above homeostatic levels in the body.
