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. Absorbs heat; endo - within






2. 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)






3. Many sugars; complex carbs






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






5. Proteins only one that are...






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






7. Matter is composed of ______






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






9. 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






10. What is chief ingredient in living things?






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






12. Dissolver (water: universal solvent)






13. Process of making two DNA molecules from one strand






14. Gives off heat; exo - outside






15. Dissolved






16. Particles are mixed but not dissolved






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






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






19. 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






20. The living content in a cell






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






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






23. Energy in motion






24. The putting together of living things






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






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






27. 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






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






29. 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 ...






30. Elements essential to life






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






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






33. 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






34. Smallest unit of an element






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






36. The ability to do work






37. Stored energy






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






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






40. The increase in randomness and loss of usable energy
