Answer:
The correct answer is C. The enzyme that ensures there is an equal distribution of newly synthesized phospholipids across the membrane is the scramblase.
Explanation:
Scramblases are proteins used to move phospholipids from one monolayer to another of the lipid bilayer inside the plasma membrane of a cell. This protein, unlike flippase, is not selective with respect to lipids but "reverses" them on the other side of the membrane in a random and non-specific manner. It therefore causes the phospholipids not to be added only on one side when the membrane is formed or expanded, but also on the opposite side in contact with the extracellular environment.
Answer:
Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge.

Homeostasis is the ability to maintain stable internal conditions
Answer:
Gene therapy is designed to introduce genetic material into cells to compensate for abnormal genes or to make a beneficial protein. If a mutated gene causes a necessary protein to be faulty or missing, gene therapy may be able to introduce a normal copy of the gene to restore the function of the protein.
