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. Particles are mixed but not dissolved






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






4. Dissolved






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






6. Stored energy






7. The living content in a cell






8. Many sugars; complex carbs






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






10. Elements essential to life






11. Matter is composed of ______






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






13. 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






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






15. 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






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






17. Absorbs heat; endo - within






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






20. 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 ...






21. The putting together of living things






22. What is chief ingredient in living things?






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. Proteins only one that are...






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






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






27. Dissolver (water: universal solvent)






28. The increase in randomness and loss of usable energy






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






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






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






32. Gives off heat; exo - outside






33. Process of making two DNA molecules from one strand






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






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






36. The ability to do work






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






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






39. Smallest unit of an element






40. Energy in motion
