| Question | Answer |
|---|---|
| Mutations | Small scale changes in DNA |
| Evolution | Change in a line of descent |
| Adaptive trait | A trait which will aid an organism in survival |
| Natural Selection | The theory that those who are best fit to their environment will be the most likely to survive and pass on their traits |
| Atom | Fundemental building block for all life |
| Molecule | Two or more atoms joined together |
| Cell | Smallest unit that can live and reproduce, also has an internal environment |
| Tissue | A group of cells interacting to preform a task |
| organ | Structural unit of two or more tissues that interact with one another to preform one or more tasks, e.g. liver, brain, kidney. |
| organ system | organs that interact in order to preform one or more tasks. e.g. the digestive system |
