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.
Theory because a theory is a well substantiated explanation of how a particular phenomenon works based on the set of facts which had been repeatedly confirmed through observations and experiments. A scientific theory gives reliable account of a phenomenon.

Answer:</u></h2>
<em>C. skeletal muscle; cardiac muscle, smooth muscle, and organs</em>
<h3><u>
Explanation:</u></h3>
- The somatic nervous system has voluntary control of body movements via skeletal muscles, whereas the autonomic nervous system is responsible for controlling involuntary body functions, such as heartbeat, blood flow, breathing, and digestion.
- Skeletal muscle system (SNS) regulating voluntary skeletal muscle contraction and autonomous nervous system ( ANS) regulating involuntary control of smooth, cardiac muscles and glands.
