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. Gives off heat; exo - outside






2. Dissolver (water: universal solvent)






3. Dissolved






4. Particles are mixed but not dissolved






5. Elements essential to life






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






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






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






9. Proteins only one that are...






10. The ability to do work






11. Matter is composed of ______






12. 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






13. The living content in a cell






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






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






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






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






18. The putting together of living things






19. Smallest unit of an element






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






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






22. 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






23. 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 ...






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






26. Many sugars; complex carbs






27. Stored energy






28. The increase in randomness and loss of usable energy






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






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






32. Process of making two DNA molecules from one strand






33. What is chief ingredient in living things?






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






35. 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






36. Energy in motion






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






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






39. 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)






40. Absorbs heat; endo - within
