2. The putting together of living things

3. Whenever energy is used - some of the energy is wasted

4. The diffusion of water(!!) through a semipermiable membrane; equilibrium is never reached.

5. Mixture of fine particles that do not settle out quickly (ex. protoplasm)

6. Matter is composed of ______

7. Stored energy

8. The increase in randomness and loss of usable energy

9. Dissolved

10. Gives off heat; exo - outside

11. Organic compounds that contain carbon - hydrogen and oxygen; provide structure and store energy

12. Made of nucleotides; sugar - phosphate - base; adenine - thyOOmine; guani`ne - cytosine

13. Elements essential to life

14. The living content in a cell

15. Homogenous(alike) mixture of one or more substances in another substance

16. The ability to do work

17. Proteins only one that are...

18. Cannot change between gel and sol (ex. egg whites)

19. Polysaccharide; animal starch (animals and humans eat starches abd break them down to monosaccharides; the liver converts them to glycogen for storage)

20. Polysaccharide; strong and flexible; makes up shells of crabs - lobsters - shrimp - insects; found in cell walls of fungi

21. Affect the rate of the reaction but are not changed in the reaction

22. Particles are mixed but not dissolved

23. Group of organic substances slightly soluble in water; very soluble in other organic liquids; mostly structural but also store energy; humans and animals store their excess energy as lipids

24. Single sugars; glucose(C6H12O6) is a monosaccharide that is manufactured by plants in photosynthesis

25. Most abundant form of lipids; building blocks for other lipids; have hydrophilic and hydrophobic ends; in water - will align themselves; good source of energy; found in dairy and animal tissues
