Biology Pre-AP

Characteristics Of Life:

• cellular struction and function
• reproduction- all living things come from other living things
• metabolism- breaking down food to absorb and use as energy (if you have a fast metabolism and use up energy fast, you're most likely skinny, and if you have a slow metabolism you don't use up your energy very fast and is most likely obese or overweight)
• homeostasis- maintaining a constant internal environment (body temperature, functions of organs, etc.)
• heredity- passing on generic materials to offspring
• evolution- change over time, not individually but as a group
• interdependence- all living things depend on other things in the environment
