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 putting together of living things






2. 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 ...






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






4. 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






5. Dissolved






6. Absorbs heat; endo - within






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






8. Gives off heat; exo - outside






9. Smallest unit of an element






10. 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






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






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






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






14. The increase in randomness and loss of usable energy






15. Process of making two DNA molecules from one strand






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






17. Elements essential to life






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






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






20. 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






21. The living content in a cell






22. 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)






23. Dissolver (water: universal solvent)






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






25. Many sugars; complex carbs






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






27. Energy in motion






28. Matter is composed of ______






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






30. Proteins only one that are...






31. 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






32. Particles are mixed but not dissolved






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






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






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






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






37. The ability to do work






38. Stored energy






39. What is chief ingredient in living things?






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