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. Process of making two DNA molecules from one strand






2. The ability to do work






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






4. Gives off heat; exo - outside






5. Matter is composed of ______






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






7. Stored energy






8. Energy in motion






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






10. Smallest unit of an element






11. 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






12. Dissolver (water: universal solvent)






13. Absorbs heat; endo - within






14. The putting together of living things






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






16. 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






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






18. Proteins only one that are...






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






20. The increase in randomness and loss of usable energy






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






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. 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)






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






25. The living content in a cell






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






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






28. Dissolved






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






30. Particles are mixed but not dissolved






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






32. 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 ...






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






34. 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






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






36. Many sugars; complex carbs






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






38. Elements essential to life






39. What is chief ingredient in living things?






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