Answer:
4) Cytoplasm
Explanation:
The cytosol (cytoplasm) is the "soup" within which all the other cell structures reside and where most of the cellular metabolism occurs.

Answer:
c. The ratio of long to short fatty acid tails in the membrane phospholipids increases
e. There is an increase in the saturation state of the fatty acid tails of membrane phospholipids
Explanation:
In biological lipid membranes, the homeoviscosity refers to the process by which the membrane 'adapts' its lipid composition to maintain a proper fluidity. It is well known that the membrane's fluidity increases with increasing temperatures. In this regard, it is important to have into account two points. First, the length of the fatty acid tail alters the membrane's fluidity: shorter fatty acid tails increase fluidity, while longer fatty acid tails decrease it (because shorter tails establish fewer molecular interactions between fatty acids tails). Second, the degree of saturation (i.e., the number of bonds between the carbon atoms) of fatty acids tails also affects homeoviscosity. A higher saturated fatty acid content decreases the membrane's fluidity because saturated tails are arranged in order to maximize molecular interactions between fatty acids tails.
The effect of differential reproduction is that there is a change of the population at the genetic level. Differential reproduction occurs because organisms have different levels of adaptation to the environment.

Similarly, around December 21, the sun is farthest south of the equator.
Around December 21
The sun's most direct rays reach farthest north or south of the equator, around December 21. This is the period of the winter solstice in the Northern Hemisphere, where the Earth is tilted away from the sun. At this time it's summer solstice in the Southern Hemisphere.
If you and a child are on a skates and you give each other a push if the mass of the child is half your mass who has the greater acceleration, then you have the greater acceleration.
