Biology Basics Quiz

The unifying themes in biology include the presence of cells processing hereditary information encoded in genes, evolution explaining the unity and diversity of life, and energy processing allowing organisms to move, grow, and reproduce. Organisms also regulate their own internal environments.

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

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