The Final Biology

2. the chemical breakdown of a substance by bacteria, yeasts, or other microorganisms, typically involving effervescence and the giving off of the heat
6. the basic unit of life
8. groups of similar cells that perform a particular function
10. the state of steady/balanced internal, physical, and chemical conditions maintained by living systems.
13. energy needed to start a chemical reaction
16. predator & prey populations regulate each other
18. can cause the entire population to “crash”
20. take reactants of an enzyme and catalyzed reaction
21. speed up a reaction
22. covers body surfaces, line body cavities, and hollow organs.
23. a group of tissues working together
24. connects, supports, and separates all other types of tissue

1. control body movements, send and receive signals
3. fiber structure allows it to contract, making the organism move.
4. the breakdown of glucose by enzymes, releasing energy and pyruvic acid
5. the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide, and water
6. trying to use a resource at the same time
7. most populations can adjust to small changes but not large or long term
9. a group of organs that work together to perform a specific function
11. similar to predators-feed at expense of the host
12. made up of many cells
14. go into a reaction
15. relating to, involving, or requiring an absence of free oxygen
17. found in every cell in your body
19. biological catalysts
