CLEP Biology

Subjects : clep, science, biology
Instructions:
  • Answer 50 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.

2. Controls olfactory lobes (smell)






3. A reaction that adds water to another compound. (2 hydrogens - 1 oxygen).

21. The pituitary gland.






22. The preservation of the integrity of genetic information from one generation to another.






23. The trachea includes the windpipe or larynx in its upper portion - and the glottis - an opening that allows the gases to pass into the two branches known as the bronchi.

26. Is a protein - which is a polymer of amino acids. They generally have the suffix -ase- like lactase.






27. Attaches to an enzyme and blocks the enzyme reaction rather than enhancing it - like a prosthetic group would.






28. The effect of a substrate concentration on the initial reaction rate in the presence of a limited amount of enzyme: _________________ as the concentration of substrate is increased until all the enzymes are used - then the reaction rate will level of






29. Carbon - nitrogen - phosphorous - and water. These are all recycled through biogeochemical processes.






30. Respiratory organs within insects






31. Are membrane-bound organelles that contain digestive enzymes that digest dead or unused material within the cell or materials absorbed by the cell for use.






32. Is the process that releases energy for use by the cell.






33. Niche

35. Contains multicellular photosynthetic eukaryotic organisms including gymnosperms and angiosperms.






36. The lineage that led to the modern Homo Sapiens diverged from the lineage that led to the modern chimpanzee.






37. The phyla of sponges.






38. A sex-linked recessive disorder carried on the x chromosome in which an individual cannot perceive certain colors.

41. The solid mass of cells resulting from the cleavage of the ovum before the formation of a blastula.






42. Where protein synthesis occurs. They float unattached in the cytoplasm. They contain RNA that is specific to their function in protein formation.






43. Is when expression of genetic traits is determined by weather the trait is inherited from the mother or the father.






44. Assumes that there are periods of stability during which little evolutionary change occurs - and that speciation can occur rapidly over a very short period of time.






45. Is composed of an anterior and posterior lobe. The stalk of the lobe is connected to the hypothalamus. Antidiuretic Hormone (AH) is produced in the hypothalamus and stored in the posterior pituitary. Upon nervous stimulation from the hypothalamus - t
