It attracts insects which in turns aid pollination.
Answer:1)Yeast cells that produce more unsaturated fatty acids than saturated fatty acids in response to cold have greater cold tolerance
2)Cell membranes in reindeer legs (near the hooves) are kept flexible because they have a large number of saturated fatty acids.
3.)Cell membranes in cold tolerant winter wheat plants have a higher ratio of unsaturated fatty acids to saturated fatty acids than do cold intolerant wheat varieties.
Explanation.
Basically the longer the chains of fatty acids the higher the degree of energy produced as heat energy, and therefore the higher the insulation.
Unsaturated fats clogged together and the aggregate carbons and hydrogens ensured insulation.
A large central vacuole, and chloroplasts.
