The carbon cycle shows how atoms of carbon can exist within different compounds at different times and be recycled between living organisms and the environment.
The specific set of alleles an organismhas makes up its genotype. Thesegenes influence the way an organism looks, which is known as itsphenotype. Phenotype is mostly aresult of an organism's genotype, but environment can also influence physical characteristics.
The one major change that occurred was the placement and organization of the electron. Rutherford's model identified that the electrons were at a distance from the nucleus, Bohr's model identified that the electrons occurred at levels that related to their available energy, and the modern atomic model shows that electrons are located in a predicted area but cannot be identified in a specific point.
Fossils are the remains or impression of the dead animals and plants that lived in the past.
