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. The living content in a cell






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






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






4. The increase in randomness and loss of usable energy






5. 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






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






7. The putting together of living things






8. Matter is composed of ______






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






10. Elements essential to life






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






12. 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






13. Energy in motion






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






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






16. 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






17. The ability to do work






18. Stored energy






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






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






21. Dissolver (water: universal solvent)






22. 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 ...






23. Smallest unit of an element






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






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






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






27. Gives off heat; exo - outside






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






29. Process of making two DNA molecules from one strand






30. Proteins only one that are...






31. Particles are mixed but not dissolved






32. 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






33. 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)






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






35. What is chief ingredient in living things?






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






37. Absorbs heat; endo - within






38. Dissolved






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






40. Many sugars; complex carbs
