Across
- 4. A cell that lacks a nucleus and membrane-bound organelles
- 5. Fundamental unit of life
- 8. Solar-powered eukaryotes!
- 9. A domain of prokaryotes, often found in extreme environments, like hot springs.
- 11. The type of feedback that counteracts a change, bringing things back to normal
- 13. The sum of all ecosystems on Earth
- 14. smaller than population but bigger than organ system
- 16. The variable you change or manipulate in an experiment. It's the one calling the shots.
- 19. An example would be all the ants in an ant pile
- 21. The process of maintaining a stable internal environment.
- 22. A group of similar cells working together, like a tiny biological work team.
- 23. Supported by a vast body of evidence. It's more than just a guess; it's practically a scientific superstar.
Down
- 1. Cellular boundary.
- 2. The process by which living things make more of themselves
- 3. Fungi and protists are examples
- 6. The kingdom to which mushrooms belong.
- 7. Genetic material found in all living organisms.
- 10. This scientific method step often involves an "if...then" statement.
