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. What is chief ingredient in living things?






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






3. The living content in a cell






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






5. 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 ...






6. 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






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






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






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






10. Absorbs heat; endo - within






11. Particles are mixed but not dissolved






12. Many sugars; complex carbs






13. Dissolved






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






15. 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






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






17. Energy in motion






18. 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






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






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






21. Process of making two DNA molecules from one strand






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






23. 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






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






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






26. Smallest unit of an element






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






28. Stored energy






29. Dissolver (water: universal solvent)






30. Matter is composed of ______






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






33. The ability to do work






34. The increase in randomness and loss of usable energy






35. Proteins only one that are...






36. Gives off heat; exo - outside






37. Elements essential to life






38. The putting together of living things






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






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