Which of the statements are true? yeast cells that produce more unsaturated fatty acids than saturated fatty acids in response to cold have greater cold tolerance. cell membranes in reindeer legs (near the hooves) are kept flexible because they have a large number of saturated fatty acids. a plant that produces more monounsaturated fatty acids than polyunsaturated fatty acids in its membranes in winter has an increased resistance to freeze damage. 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.

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.

lunar landing mission. apollo 11 was the first manned mission to land on the moon. the first steps by humans on another planetary body were taken by neil armstrong and buzz aldrin on july 20, 1969. the astronauts also returned to earth the first samples from another planetary body.
