Describe in detail the process of Natural Selection / Evolution.
saveliy_v [14]

Natural Selection is the process by which the most adapted, or fittest, species survive and the least adapted, or unfit, species do not survive. An example of Natural Selection is if there are two species of birds that eat the same thing, but one of the species has a beak that makes it harder to eat the food, naturally the species that has the beak fit to eat that food will survive. The species that is not fit to eat that food will either adapt or will be unable to survive. Evolution is a species adapting to the enviornment over a period of time. There is microevolution and macroevolution.

Explanation:

Seawater is the most clear example of a hypertonic solution in nature. The concentration of ions in seawater are far more superior than the concentration of ions inside a plant or an animal cell, since seawater have an osmolarity of about 1000 mOsm/l. Therefore, at high tide a plant or animal cell will be in a hypertonic solution, and the cells must have adaptions to avoid cell shrinking and dead.
