3. A statement about expected outcomes of an experiment.
4. A statement proposing an explanation (educated guess) toward the solution of an observation.
5. A useful, testable explanation based on a related set of accepted, scientific conclusions
6. Capacity of cells to extract energy from sources in their environment by chemical reactions
7. The ability of organisms to determine whether an environment is positive or negative
8. A state in which the internal environment is not being maintained within tolerable limits
9. Characteristic of life that is questioned concerning whether viruses are living or not living
10. Improves chances to survive and reproduce in a specific environment.
You are a fish culturist working on developing a new treatment to prevent bacterial kidney disease (BKD). After
years of work you develop a drug, which will kill the bacteria that cause BKD. To test your drug, you take one
group of fish and inject them with the drug and place them in TANK A. Another group of fish are injected with
water and are place into TANK B. Every other week you sacrifice 5 fish from each tank and look for BKD.

13. Controlled variable
14. Independent variable

21. When you are trying to understand something new, you begin by observation, and then put the observations together
in a logical fashion to form a general principle. This method of logic is called
