Warm air rises, expands, then cools. As cool air sinks it may cause precipitation. Some air masses such as the MT which originate in warm environments carry humid air and cause heavy precipitation in some areas.
Answer:
The correct option is <em>B. Cholesterol is non-polar.</em>
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.
