Biology is a vast subject containing many subdivisions, topics, and disciplines. Among the most important topics are five unifying principles that can be said to be the fundamental axioms of modern biology:1.Cells are the basic unit of life2.New species and inherited traits are the product of evolution3.Genes are the basic unit of heredity4.An organism will regulate its internal environment to maintain a stable and constant condition5.Living organisms consume and transform energy.Subdisciplines of biology are recognized on the basis of the scale at which organisms are studied and the methods used to study them: biochemistry examines the rudimentary chemistry of life- molecular biology studies the complex interactions of systems of biological molecules- cellular biology examines the basic building block of all life, the cell- physiology examines the physical and chemical functions of the tissues, organs, and organ systems of an organism- and ecology examines how various organisms interact and associate with their environment.
