CLEP Biology: Basic Chemistry

Subjects : clep, science, biology
Instructions:
  • 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. Mixture of fine particles that do not settle out quickly (ex. protoplasm)






2. The ability to do work






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






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






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






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






7. Proteins only one that are...






8. Matter is composed of ______






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






10. Process of making two DNA molecules from one strand






11. Elements essential to life






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






13. Dissolved






14. 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)






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






16. The putting together of living things






17. Smallest unit of an element






18. What is chief ingredient in living things?






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






20. Gives off heat; exo - outside






21. 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






22. 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 ...






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






24. Many sugars; complex carbs






25. Absorbs heat; endo - within






26. 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






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






28. Energy in motion






29. 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






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






31. 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






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






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






34. The living content in a cell






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






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






37. Dissolver (water: universal solvent)






38. Particles are mixed but not dissolved






39. Stored energy






40. The increase in randomness and loss of usable energy
