5. Biology: the Study of Life Cellular Structure (cell = unit of life) Metabolism = Homeostasis (PSN, Resp, N 2 fix, ferment, etc.) Growth = irreversible change in size Movement…includes internal, limbs, locomotion Reproduction…failure = extinction Acclimatization-short term responses = behavior Adaptation-long term responses = evolution What are the fundamental properties of life?

6. Biology is multidimensional Cell Tissue Organ Organ System Organism Population Community Ecosystem This array is an example of what dimension? Levels of Organization What fields of biology are at each extreme? Biochemistry and Biophysics In this course our focus will be upon… The Organism!
