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






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






3. Process of making two DNA molecules from one strand






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






5. 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






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






7. The living content in a cell






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






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






10. 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






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






12. Stored energy






13. 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 ...






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






15. 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






16. The putting together of living things






17. Absorbs heat; endo - within






18. Particles are mixed but not dissolved






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






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






21. Many sugars; complex carbs






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






23. Elements essential to life






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






25. Proteins only one that are...






26. Matter is composed of ______






27. 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






28. The ability to do work






29. Energy in motion






30. Smallest unit of an element






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. Gives off heat; exo - outside






33. The increase in randomness and loss of usable energy






34. Dissolved






35. What is chief ingredient in living things?






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






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






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






39. Dissolver (water: universal solvent)






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