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. Many sugars; complex carbs






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






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






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






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. 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






7. Process of making two DNA molecules from one strand






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






9. Gives off heat; exo - outside






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






11. The increase in randomness and loss of usable energy






12. Elements essential to life






13. The ability to do work






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






15. Stored energy






16. Proteins only one that are...






17. 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






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






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






20. The living content in a cell






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






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






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






24. Particles are mixed but not dissolved






25. 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






26. Absorbs heat; endo - within






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






28. What is chief ingredient in living things?






29. Smallest unit of an element






30. Dissolver (water: universal solvent)






31. 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






32. 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)






33. The putting together of living things






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






35. 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 ...






36. Energy in motion






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






38. Dissolved






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






40. Matter is composed of ______
