Document Summary
Living organisms (cells) transform energy from one form to another to do work. Energy flows through an ecosystem, usually enters as light and exits as heat. Structure and function are correlated at all levels of biological organization. The (cid:272)ell is a(cid:374) orga(cid:374)is(cid:373)"s (cid:271)asi(cid:272) u(cid:374)it of stru(cid:272)ture and function. The cell is the lowest level of organization that can perform all activities required for life. The continuity of life is based on heritable information in the form of dna. Genes units of inheritance that transmit information from parents to offspring. Differences among organisms are due to accumulation of heritable changes.

Evolution through natural selection is not random process. Observations and inductive reasoning can lead us to ask questions. A hypothesis is a tentative answer (proposition) to a well-framed question. A scientific hypothesis leads to predictions that can be tested by observation or experimentation.
