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






2. The putting together of living things






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






4. Elements essential to life






5. Process of making two DNA molecules from one strand






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. The ability to do work






8. Particles are mixed but not dissolved






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






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






11. 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)






12. 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






13. The living content in a cell






14. Dissolved






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






16. Many sugars; complex carbs






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






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






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






20. Dissolver (water: universal solvent)






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






23. 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






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






25. Matter is composed of ______






26. 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






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






28. Gives off heat; exo - outside






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






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






31. Energy in motion






32. Absorbs heat; endo - within






33. Proteins only one that are...






34. Smallest unit of an element






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






36. Stored energy






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






38. The increase in randomness and loss of usable energy






39. What is chief ingredient in living things?






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