Which of these biomolecules increase membrane fluidity and help prevent the cell membrane from freezing?
cholesterol
saturated fat
O unsaturated
fat
U DNA

Cholesterol

Explanation:

Cholesterol is a lipid molecule produced by the liver, then transported to the membranes of animal cells. Cholesterol, which is found embedded in the plasma membrane of animal cells alongside other molecules like phospholipids, plays a vital role there.

The cholesterol of animal cell membranes help increase the fluidity of the membrane and also helps prevent the membrane from freezing during low temperatures.

x would be the most and the least would be y because there are more fruit   and seeds than flock z has insects

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
