In order for natural selection to take place we must have "variety in a population". This variety of traits is what allows natural selection to "pick" the most favorable traits.
Adenosine triphosphate (ATP) connects anabolism and catabolism in cells by storing energy from catabolic reactions and providing that energy to anabolic reaction.
Adenosine triphosphate (ATP), also known as energy molecule, is found in animal and plants cells.
It plays a huge role in anabolic and catabolic reactions.
During anabolic reaction, simple organic molecule join together to form complex molecule by using energy.
For example, carbohydrates, fats, proteins and glycerol.
While in catabolic reaction, large complex molecules disintegrate to form small molecule and in this reaction a large amount of energy is released.
This energy is stored by the body cells for later use.

The importance of the semi-conservative model is unhealthy old and new genes cancel each other. The result new cells are disease and mutation free. ... DNA replication is semiconservative because DNA is composed of two complementary strands, each of which acts as template to construct a new strand complementary to itself.
Its b. Ecosystem
Population is the number of a species in an area, it has nothing to do with physical characteristics.
Abiotic is just an adjective meaning not alive
Competition is just the interactions between organisms in the struggle for food, water, space, mates, and many other things again not physical characteristics
