Answer:
The small molecules such as water and carbon dioxide can easily or directly pass through the membrane because they are neutral and so small. the movement of water through the membrane is referred to as osmosis. water can also pass through the membrane through channel protiens called aquaporins (AQP).
Explanation:
Natural selection is the process that result in the adaptation of an organism to environment by means of selectively reproducing changes in its genotype, or genetic constitution. It is the a key mechanism of evolution. Charles Darwin popularised the term "natural selection" contrasting it with artificial selection, which is intentional, whereas natural selection is not.
To make it simple, let's have a group of beetle composing of green and some are brown as an example. here, there is a variation in traits. Since the environment could not support continuous population growth, not all species can reproduce to their full potential. Green beetles can easily be eaten by other species like birds compared to brown beetles. The surviving brown beetles will then generate brown offsprings because their trait has a genetic basis. Since more brown beetles survive and becomes more common in the population, the process continues until all individuals will eventually be brown. so basically, if you have variation, differential reproduction, and heredity, you will have evolution by natural selection as an outcome.
improved soil fertility
Explanation:
One direct benefit of biodiversity is improved soil fertility. Biodiversity is the variety of plants and animals living in a particular ecosystem.
A soli is made up of organic matter. Organic matter is the remain of dead and decaying plant and animal materials in the soil.
Organic matter is a very important soil component.
Since plants and animals eat up plants which takes nutrients from the soil, there must be a way to replenish these vital soil materials.
The more biodiverse an ecosystem, the better its chance of adding more nutrients to the soil as they decay.
