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






2. Proteins only one that are...






3. Smallest unit of an element






4. 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






5. 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)






6. The putting together of living things






7. Particles are mixed but not dissolved






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






9. Absorbs heat; endo - within






10. Matter is composed of ______






11. Dissolved






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






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






14. 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






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






16. Process of making two DNA molecules from one strand






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. Another nucleic acid; single strand; sometime replaces thymine






19. Gives off heat; exo - outside






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






21. Elements essential to life






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






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






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






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






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






27. The ability to do work






28. What is chief ingredient in living things?






29. 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






30. Dissolver (water: universal solvent)






31. Energy in motion






32. The living content in a cell






33. Many sugars; complex carbs






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






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






36. Stored energy






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






38. The increase in randomness and loss of usable energy






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