Natural Selection : Concept was given by Darwin. Differetial rate of reproduction among species results into selection one species which is termed as natural selection. Due to limited resources of food and space there is always struggle for existance. Species which is better adapted to environment survives and in due course of time it results into origin of new species.

Cell: It is the basic unit of life. There are two types of cells - somatic and germ cell. Somatic cell divides by mitosis and germ cell divide by meiosis. Cell together form tissue which in turn from different organ.

Solution Summary

Darwin proposed theory of natural selection of evolution
Bioenergetics is the subject of a field of biochemistry that concerns energy flow through living systems
Homeostasis is the property of either an open system or a closed system, especially a living organism, which regulates its internal environment so as to maintain a stable, constant condition.
Mendel proposed the theory of inheritance and he is known as father of genetics.
