| Human Life Cycle | infancy, childhood, adolescence, adult, senior |
| Incomplete metamorphosis | animals hatch and look like an adult but they don't have all the adult parts EX: grasshoppers don't have wings when they hatch |
| Inherited traits | traits that can not be changed. Examples: eye color |
| learned behaviors | things that you learn because of what you see and hear. Example: speaking English |
| Life Cycle | the stages a living thing goes through Example: seed to seedling stage to flowering stage to fruit |
