Answer:
Natural selection is the process in nature by which organisms better adapted to their environment tend to survive and more than those less adapted to their environment. For example :treefrogs are sometimes eaten by snakes and birds
Hope this helps
Answer:
The tree main cell components are: plasma membrane, cytoplasm and nucleous
Explanation:
The plasma membrane is the a bilipid membranous layer composed of proteins and carbohydrates.

The nucleous is an organelle which contains genetic information (DNA) on special strands called chromosomes.
<span>There are three parts of the body that will change suggesting a systemic disease. The first is the hands, which contain may blood vessels and a significant amount of skin surface. Nerves in the body might show signs of a systemic disease. Finally, muscles, tendons and ligaments might swell or otherwise show signs of bodily stress.</span>
When we talk about evolution we come across the process of natural selection. Genetic variation is always required for the natural selection. A change or variation in the genes may help the individuals in a population to better adapt to the environment. Such changes may be brought by mutations or random mating in the population. Such variations help in the survival of the population by allowing them to adapt to changing environmental conditions.
