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






2. Dissolver (water: universal solvent)






3. 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)






4. Many sugars; complex carbs






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






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






7. The putting together of living things






8. Smallest unit of an element






9. The living content in a cell






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






11. Energy in motion






12. Absorbs heat; endo - within






13. 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






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






15. The increase in randomness and loss of usable energy






16. Matter is composed of ______






17. Stored energy






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






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






20. Gives off heat; exo - outside






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






22. Proteins only one that are...






23. The ability to do work






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






25. Particles are mixed but not dissolved






26. Process of making two DNA molecules from one strand






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






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






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






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






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






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






33. 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






34. Elements essential to life






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. Dissolved






38. 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 ...






39. What is chief ingredient in living things?






40. 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
