Biology: The Study of Life

The unifying themes in biology include the concept that all organisms are made up of cells processing hereditary information, evolution as the explanation for the unity and diversity of life, the importance of energy processing, and the ability of organisms to regulate their internal environments.

Biologists use the scientific method to make observations, pose questions, generate hypotheses, perform experiments, and form conclusions about the world around them.

Biologists study life at multiple levels of organization, from the molecular biology of a cell to the anatomy and physiology of plants and animals, and the evolution of populations.
