3. What is alive? All living things: Are made up of cells Reproduce
Are based on genetic codes
Grow and develop
Require energy and materials (nutrition)
Respond to their environment
Maintain stable internal environments
As groups, change over time
Remove waste

4. Cell- A group of small living matter within a barrier.
Cells are the smallest unit of structure
and function in all living things.

5. Reproduction- Sexual Reproduction- When two parents

Metabolism- a combination of MANY chemical reactions the body goes through to obtain the energy for life.
The process of obtaining the materials needed for these reactions is called “nutrition”

7. Maintaining balance-
Homeostasis- the process by which organisms maintain a relatively stable internal environment.
Dynamic Equilibrium- The environment’s “homeostasis”, with all things keeping themselves in check.

8. Change over time-
As a GROUP, all organisms must change over time, or EVOLVE, allowing them to be better suited to survive in their environment.
*They do NOT adapt- most die, and some are lucky enough to have the tools to survive
