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. Process of making two DNA molecules from one strand






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






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






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






6. Dissolver (water: universal solvent)






7. 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 ...






8. Matter is composed of ______






9. Energy in motion






10. Many sugars; complex carbs






11. What is chief ingredient in living things?






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






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






14. Stored energy






15. Particles are mixed but not dissolved






16. The increase in randomness and loss of usable energy






17. Dissolved






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






19. Proteins only one that are...






20. Absorbs heat; endo - within






21. 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






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






23. The ability to do work






24. Elements essential to life






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






26. 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






27. Gives off heat; exo - outside






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






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






31. 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)






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






33. The living content in a cell






34. Smallest unit of an element






35. The putting together of living things






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






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






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






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






40. 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
