CLEP Biology: Basic Chemistry

Subjects : clep, science, biology
Instructions:
  • Answer 40 questions in 30 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. Another nucleic acid; single strand; sometime replaces thymine






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






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






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






5. Elements essential to life






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






7. What is chief ingredient in living things?






8. The putting together of living things






9. Proteins only one that are...






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






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






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






13. Absorbs heat; endo - within






14. Energy in motion






15. The increase in randomness and loss of usable energy






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






17. 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






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






19. Process of making two DNA molecules from one strand






20. The living content in a cell






21. Matter is composed of ______






22. Gives off heat; exo - outside






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. 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






25. Dissolved






26. The ability to do work






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






28. 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






29. Dissolver (water: universal solvent)






30. Many sugars; complex carbs






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






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






33. 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






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






35. Particles are mixed but not dissolved






36. 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 ...






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






38. Smallest unit of an element






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






40. Stored energy
