With stabilizing selection, the phenotype for a trait does not influence survival. Stabilizing selection reduces the amount of variation in a trait. Disruptive selection increases the amount of variation in a trait. With stabilizing selection, extreme individuals have high biological fitness.
Directional Selection When the environment changes, populations will often undergo directional selection, which selects for phenotypes at one end of the spectrum of existing variation. Stabilizing Selection If natural selection favors an average phenotype by selecting against extreme variation, the population will undergo stabilizing selection. For example, in a population of mice that live in the woods, natural selection will tend to favor individuals that best blend in with the forest floor and are less likely to be spotted by predators. Assuming the ground is a fairly consistent shade of brown, those mice whose fur is most-closely matched to that color will most probably survive and reproduce, passing on their genes for their brown coat. Mice that carry alleles that make them slightly lighter or slightly darker will stand out against the ground and will more probably die from predation. As a result of this stabilizing selection, the population’s genetic variance will decrease. Diversifying (or Disruptive) Selection Sometimes natural selection can select for two or more distinct phenotypes that each have their advantages. In these cases, the intermediate phenotypes are often less fit than their extreme counterparts. Known as diversifying or disruptive selection, this is seen in many populations of animals that have multiple male mating strategies, such as lobsters. Large, dominant alpha males obtain mates by brute force, while small males can sneak in for furtive copulations with the females in an alpha male’s territory. In this case, both the alpha males and the “sneaking” males will be selected for, but medium-sized males, which cannot overtake the alpha males and are too big to sneak copulations, are selected against

Option C . Flip-flops are very rare for phospholipids.
Explanation:
Flip-flop means that movement of phospholipds upside down. This phenomenon occur in cell membrane but very rarely. I have attached a picture for you to under stand how flip-flopping occurred.
Homeostasis is the a resistance to change due to the body's attempt to maintain constant and stable internal environment. To maintain the body's overall functioning it is very important that homeostasis is maintained at all levels.
Body temperature can be used as homeostasis parameter in the lab. It is important that that the body tries to maintain a constant temperature.
