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.
1. Controls balance and muscle coordination






2. Super-class of vertebrae including organisms with no jaws.






3. The number of organisms in a given community - can be above or below the carrying capacity.






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






5. The total amount of genetic information available for a given species.






6. Approximately 7 - making it neither basic (under 7) nor alkaline (over 7).






7. Carbon - Hydrogen - Oxygen - and Nitrogen






8. 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






9. The sharp boundary of an ecosystem.






10. Is a behavior that is learned during a critical point (often very early) in an individual's life. Imprinting enables the young the recognize members of their own species.






11. Subsets below the kingdom level






12. Anabolism






13. Mitochondria - they constitute the center of cellular respiration.

14. Protein synthesis






15. Mass extinctions promote diversification because _______________ - making conditions favorable for the establishment of new - diverse species.






16. Small - green - heart-shaped gametophyte plant form of a fern that can make its own food and absorb water and nutrients from the soil






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






18. Super-class of vertebrae including organisms with jaws.






19. (of some plants or fungi) feeding on dead or decaying organic matter






20. Absorb a photon of light and is found in the grana of the chloroplast.






21. Covalent bonds






22. Is a kind of plain characterized by a warm climate - grassland - and seasonally dry climate conditions.






23. Are the organelles where cellular respiration occurs.






24. Sex-linked recessive disorder carried on the x chromosome defined by the absence of one or more proteins required for blood clotting






25. Are where the sugars synthesized by photosynthesis travel through to various parts of the plant.






26. Some patrol the blood for antigens - but are also equipped to destroy antigens. They may regulate immune responses as well.






27. Energy transformations that occur as chemicals are broken down or synthesized within the cell.






28. May be ions or non-protein molecules - they are similar to cofactors - but differ in that they are tightly attached by covalent bonds to the enzyme - rather than being separate atoms or molecules.






29. Is the number of organisms that can be supported within a particular ecosystem.






30. The individual we recognize as an adult fern.






31. The phyla of round worms.






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






33. Is more like branching out of a tree with dead ends and new branches appearing simultaneously than like steps on a ladder.






34. Allows for the genetic code to be preserved in future generations of cells.






35. 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.






36. States that where random mating is occurring within a population that is in equilibrium with its environment - the gene frequencies and genotype ratios will remain constant from generation to generation. It is a mathematical formula that shows why re






37. Is a phylum that contains jellyfish - hydra - etc.






38. Are the monomers that form nucleic acids - containing a sugar - phosphate group - and a nitrogenous base.






39. The physical place where a particular organism lives. It must include all the factors that will support its life and reproduction.






40. A suffix meaning 'to break apart.' O || ||






41. In both living and non-living environments.






42. Has loosely packed cells that allow for gas and moisture exchange.






43. Consists of undifferentiated cells capable of quick growth and specialization. It is responsible for elongation of the stem.






44. The cells of a developing embryo (at the gastrula stage) differentiate into layers - that will later develop into different tissues and organs - including the mesoderm - ectoderm - and endoderm.






45. In order to become an established part of an island ecosystem there must be a populations large enough to ensure _________ - a food source - a suitable habitat - and a source of moisture.






46. Is a compound fruit that forms from several ovaries of separate flowers that fuse together during ripening (strawberry - or pineapple).






47. Contains organisms that are multicellular eukaryotes including molds and mushrooms.






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






49. Is an ion that binds to an enzyme making it more able to catalyze a reaction.






50. Process of breaking down complex materials (foods) to form simpler substances and release energy.
