Answer
Complex barrier to the flow of substances out of the cells,and restrictions to inflow of unwanted substances into the cells. The hydrophobic and hydrophilic nature of the cell membrane controls the entry of substances from the extracellular medium into the intracellualr. In addition the polarity restricts certain substance movement across the walls.
Serve as the selective channels for the influx of certain substances into the cells, and the out flux of wastes.This is through ion channels for the movements of ions across.
Provide insulation to the cells,to maintain the constant internal temperature,this is through the presence of lipids as( Phospholipids and cholesterol).The latter prevent the clogging of the lipids in the cell membrane therefore preventing frozen up of the cell membrane,providing insulation.
Separation of metabolic process in the cell.
Explanation:
Cell membrane-This is present in all cells.But the variation of its constituents makes it unique to each cell. Although it performs the same role, the location and role the cells it bounded, reflects its constituents, it is made up of lipids, carbohydrate, protein and cholesterol
The correct answer is A: cell
This phenomenon can be explained by Allen's rule. It says that the body proportions and shape may vary in different climates. The temperature decreases as the latitude increases, so in the northern region is much colder. Animals must preserve heat in such conditions. So, exposed surface areas of the body, such as the ears, feet, and tail, are usually minimized to minimize heat loss in the cold climate. <span>Therefore, northern species often have smaller ears, feet, and tail than the southern species. </span>
The answer to the above question is Genes for traits conferring an advantage to local conditions are unlikely.

What is genetic diversity?</h3>
Genetic diversity refers to the total number of genetic traits that make up a species' genetic composition. It varies greatly depending on the number of species present as well as across species, and it can be linked to a species' longevity. It differs from genetic variability, which is the propensity for hereditary traits to change.
The ability of populations to adapt to changing circumstances is facilitated by genetic variety. More variation increases the likelihood that certain members of a group will have allele variants that are appropriate for the environment. Those people have a higher chance of living long enough to have children who carry that allele. The success of these people will allow the population to continue for longer generations.
