If you want what it does it protects the cells from its surroundings, It's made of embedded proteins I believe. Hope that helped please answer my question.
Rabbits produce large numbers of offspring during each reproductive season, yet the number of rabbits within a given population changes very little from year to year. The stability of the population size is most likely the result of environmental factors that keep the population in check (2). Rabbits are seen as food by many predators which will keep the numbers down. The principle of the survival of the fittest will ensure that young strong rabbits get to breed and carry the gene pool to the next generation.
