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






2. 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






3. The putting together of living things






4. Dissolver (water: universal solvent)






5. Energy in motion






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






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






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






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






11. Stored energy






12. Dissolved






13. Elements essential to life






14. Many sugars; complex carbs






15. Process of making two DNA molecules from one strand






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






17. The living content in a cell






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






19. 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






20. Absorbs heat; endo - within






21. 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 ...






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. 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






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






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






26. 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)






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






28. Smallest unit of an element






29. Particles are mixed but not dissolved






30. Matter is composed of ______






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






32. Gives off heat; exo - outside






33. Proteins only one that are...






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






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






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






37. The ability to do work






38. The increase in randomness and loss of usable energy






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






40. What is chief ingredient in living things?
