framework of understanding
All the branches of biology can be unified within a framework of five basic understandings about living things
FRAMEWORK OF UNDERSTANDING
the cell is the basic unit of life, all living things are composed of cells, and all cells arise from pre-existing cells.
All living things require energy, and energy flows between organisms and between organisms and the environment.
All living things have DNA and genetic information codes the structure and function of all cells.
All living things must maintain homeostasis, a state of balanced equilibrium between the organism and its environment.
Evolution is the change over time that is the engine of biological diversity.
