Biological Theories 1 - Theory Concept Cell All organisms are composed of cells and new cells only come from preexisting cells Gene Organisms contain coded information that dictates their form, function, and behavior Evolution All living things have a common ancestor, but each is adapted to a particular way of life Homeostasis The internal environment of an organism stays relatively constant – with a range protective of life Ecosystem Organisms are members of populations that interact with each other and with the physical environment within a particular locale
