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. Absorbs heat; endo - within






2. What is chief ingredient in living things?






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






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






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






6. The ability to do work






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






8. 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 ...






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






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






11. Many sugars; complex carbs






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






13. Dissolver (water: universal solvent)






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






15. Proteins only one that are...






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






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






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






19. Energy in motion






20. The putting together of living things






21. The increase in randomness and loss of usable energy






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






23. 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






24. Gives off heat; exo - outside






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






26. 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






27. Particles are mixed but not dissolved






28. The living content in a cell






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






30. Dissolved






31. Smallest unit of an element






32. Stored energy






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






34. 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)






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






36. Elements essential to life






37. Matter is composed of ______






38. 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






39. 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






40. Process of making two DNA molecules from one strand
