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






2. Matter is composed of ______






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






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






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






6. The putting together of living things






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






8. 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






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






10. 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






11. What is chief ingredient in living things?






12. Absorbs heat; endo - within






13. Dissolver (water: universal solvent)






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






15. 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 ...






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






17. The living content in a cell






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. Many sugars; complex carbs






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






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






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






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






24. Energy in motion






25. Particles are mixed but not dissolved






26. Elements essential to life






27. Gives off heat; exo - outside






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. Proteins only one that are...






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






32. Smallest unit of an element






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. 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






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






36. The ability to do work






37. Dissolved






38. Stored energy






39. The increase in randomness and loss of usable energy






40. Process of making two DNA molecules from one strand
