Answer:
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.
Yeast cells that produce more unsaturated fatty acids than saturated fatty acids in response to cold have greater cold tolerance.
Explanation:
The organisms which live in cold environment must have more amount of unsaturated fatty acids as compared to saturated fatty acids because <u>unsaturated fatty acids tend to freeze at comparatively lower temperature which provides the organisms an advantage and better adaptability to live in such environments. </u>The unsaturated fatty acids will not freeze easily even in cold environment and their body/cell will keep working perfectly even in cold weather. In contrast to this, the saturated fatty acids will freeze easily and the whole system of that organism will collapse during winter season.
Same goes with yeast. more unsaturated fatty acids in the body as compared to saturated fatty acids will help the yeast to live in cold environment. The reason for better adaptability is same as above.

Answer:
Polygenic
Explanation:
Mental illnesses are almost always polygenic, meaning they are influenced by many genes.
It is also important to note that most mental illnesses have hereditary components, but to become a disease a combination of multiple environmental factors and mutations in several genes, usually from different chromosomes, must occur.
Answer:
<h2>C. A slow heart rate increases end diastolic volume, stroke volume, and force of contraction.</h2>
Explanation:
Cardiac output: The volume of blood the heart pumps via the circulatory system per minute is known as cardiac output.
Stroke volume : The volume of blood ejected by the left ventricle in one contraction is called or known as stroke volume and it with heart rate defines the cardiac output.
Cardiac output, is : A slow heart rate increases end diastolic volume, stroke volume, and force of contraction.
