Cholesterol is polar.

Cholesterol is repelled by the polar tails.

Answer 1

Answer:

The correct option is B. Cholesterol is non-polar.

Explanation:

Cholesterol is a non- polar substance and due to this property it is an active part of the cell membrane. Cholesterol molecules help to maintain the stability of a cell. When the temperatures are high, cholesterol stops the cell membrane from crystallization. When the temperatures are low, cholesterol reduces the packaging of molecules of phospholipids. As a result, fluid phase is archived by the cell membrane.
