Explanation:

apex approved proof it is really right below

Answer;

-Arctic microbes would have membranes with more unsaturated fatty acids;

Explanation;

-Increasing the unsaturated fatty acid ratio would make it harder for the fatty acids to pack together. This will keep the membrane fluid at lower temperatures, which will benefit organisms that live in very cold climates.

-At low temperatures, cholesterol increases membrane fluidity by preventing membrane lipids from packing close together. At high temperatures, cholesterol decreases membrane fluidity.
