Answer:
Plasma membrane is the semi-permeable membrane that allow the movement of some selected particles only against the concentration gradient or along the concentration gradient.
Different substances can be move through the diffusion, active process and passive process. The hydrogen in the vesicle has been moved through the facilitated diffusion. In this process, the hydrogen ions will move along the concentration gradient without the requirement of energy but requires the channel protein for its transport.
Answer:
The cell membrane will fold over a substance or particle until it becomes completely enclosed by the membrane
Explanation:
Endocytosis is when a substance or particle from the outside is captured and engulfed by the cell membrane until it is in the inside.
Since the means of reproduction have changed, the population of peacocks would probably start losing their pretty feather colors due to the fact that over time females would be mating with the containing the other trait (and possibly not the pretty feathers).

This would continue on and on until those with the desired trait outnumbered or possibly extinguished the now unnecessary vibrant feather colors.
In biotechnology, the process of introducing the foreing DNA into a cell by a virus is called transduction.Gene therapy is one of the purposes of this process.
