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. Proteins only one that are...






2. The living content in a cell






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






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






5. The putting together of living things






6. Process of making two DNA molecules from one strand






7. 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






8. What is chief ingredient in living things?






9. Matter is composed of ______






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






11. Gives off heat; exo - outside






12. Dissolver (water: universal solvent)






13. 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






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






15. Stored energy






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






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






18. The increase in randomness and loss of usable energy






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






20. The ability to do work






21. Elements essential to life






22. 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






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






24. 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






25. Many sugars; complex carbs






26. Smallest unit of an element






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






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






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






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






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. Energy in motion






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






34. 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 ...






35. Dissolved






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






37. Absorbs heat; endo - within






38. 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)






39. Particles are mixed but not dissolved






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