Cholesterol is one of the molecules composing the cell membrane. b) makes the cell membrane fluid at room temperature.
<h3>What is the role of cholesterol in the cell membrane?</h3>
The cell membrane is composed of two lipidic bilayers, cholesterol, proteins, and glucans incrusted in between.
Cholesterol is one type of lipid.
These molecules are incrusted in the membrane between the hydrophobic tails of lipids.
Their proportion on both sides of the membrane is almost the same.
Cholesterol is a significant molecule that contributes to the membrane fluidity, separates phospholipids, and interact with membrane proteins regulating in their activity.
The correct option is b). makes the cell membrane fluid at room temperature.

Answer:
Renewable Energy Resources.
Explanation:
Unlike fossil fuels which cannot be recovered when destroyed, these sources of energy can be recovered by a means of recycling . Recycling here reduces solid wastes which is one of the causes of land pollution.
Hydroelectric schemes can only be built in mountain regions where rainfall and rivers are plentiful which involves upset of aquatic ecosystem. This poses a dangerous pollution problem though.
Wind generators and solar panels are not very efficient energy producers. However, future schemes for producing solar energy via solar satellites are promising.
They should be limited to suit your needs not overdoing it or underdoing just to a healthy weight.
