CLEP Biology: Basic Chemistry

Subjects : clep, science, biology
  • Answer 40 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. The increase in randomness and loss of usable energy

2. The living content in a cell

3. The putting together of living things

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

5. Another nucleic acid; single strand; sometime replaces thymine

6. Dissolver (water: universal solvent)

7. Matter is composed of ______

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

9. When a cell needs a monosaccharide - enzymes cause disaccharides to undergo hydrolysis - which means the breaking down of a disaccharide by adding a water molecule

10. Particles are mixed but not dissolved

11. Process of making two DNA molecules from one strand

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

13. Is a polysaccharide; stored by plants; a major energy source for humans; humans can't make it

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

15. Smallest unit of an element

16. Many sugars; complex carbs

17. Dissolved

18. Composed of long chains of glucose; is a polysaccharide; found in plant cell walls; nondigestible by most animals; part of our diet called bulk or rubbage(fiber)

19. Can change between gel and sol phases (ex. protoplasm)

20. Energy in motion

21. Stored energy

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

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

24. Made of amino acids; polypeptide chain of amino acids; make up the majority of an organism's cells; used as enzymes or as building blocks

25. In any process - energy is neither created nor destroyed

26. Elements essential to life

27. 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

28. The ability to do work

29. Gives off heat; exo - outside

30. Proteins only one that are...

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

32. What is chief ingredient in living things?

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

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

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

36. 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

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

38. Found in nucleus of cell; contain info necessary for the manufacture of an organism's proteins; nucleic acid form genes; watson and crick discovered

39. Double sugars; maltose - sucrose - lactose; formed when monosaccharides undergo dehydration synthesis - when a suger looses hydrozyl group (OH) and another gives hydrogen - resulting in a water molecule and a ...

40. Absorbs heat; endo - within
