Document Summary

Are composed of cells: single cell organisms, multi celled organisms, maintain homeostasis, a stable internal environment, respond to their external environment, organisms react, cells have specialized and specific functions, bloods volume, ph, water balance, temperature. Chapter 1: have a different molecular structure than nonliving things, require energy and raw materials, all living things use energy, metabolism: chemical reactins, chemical energy (food): heat and mechanical energy, plants + light energy(sun): chemical energy(sugars, light, temp, odor, sound, gravity, heat, water, pressure, grow and reproduce, all living things undergo stages of growth and development, determined b. by their own genetic codes. Involves a change in physical form or physiological make up of an organism: we all started off as a zygote, fertilization: fusion of a fathers sperm with a mothers egg, growth and development follows, populations evolve, evolution: change in a population over time.
