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






2. Is a kingdom that includes algae and protozoa.






3. 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.






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






5. The systematic search for individuals with a specific genotype in a delineated population.






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






7. Internally generated patterns of body functions - including hormonal signals - sleep - blood pressure - and temperature regulation - which have approximately a 24-hour cycle and occur even in the absence of normal cues about whether it is day or nigh






8. Are surrounded by capillaries that allow for carbon dioxide to diffuse into the lungs and oxygen to diffuse out.






9. Is the organelle where cellular reproductive processes occur.






10. Include: Vascular tissue - including both xylem and phloem - and sieve plates existing between cells of the stem.






11. Carbon - Hydrogen - Oxygen - and Nitrogen






12. Subsets below the kingdom level






13. Anabolism






14. Is a coenzyme required in the synthesis of collagen.






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






16. Transfers water and does not require sieve plates to allow nutrients through.






17. The sharp boundary of an ecosystem.






18. All store energy within their chemical bonds.






19. The process whereby cells build molecules and store energy (in the form of covalent chemical bonds).






20. 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.






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






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






23. Produce seeds without flowers. They include conifers (cone-bearers) and cycads.






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






25. Channels is cell membranes that carry water between cells.






26. Covalent bonds






27. 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






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






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






30. Is the period when the cell is active in carrying on the function it was designed to perform within the organism. Cells spend much more time in interphase than in cell division.






31. Contain one celled eukaryotes such as algae and protozoa.






32. 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.






33. Contains many genes and is a structure comprised of linear DNA and associated proteins.






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






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






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






37. Protein synthesis






38. Is very rare and is not absorbed by plant leaves. Phosphorous is nearly always found in solid form.






39. Is composed of a double layer (bilayer) of phospholipids with protein globules imbedded within the layers. The construction of the membrane allows it to aid the function of the cell by permitting entrance and exit of molecules as needed by the cell.






40. Niche






41. Are tubes constructed of a geometrical arrangement of microtubules in a pinwheel shape. Their function includes the formation of new microtubules - but is primarily to form the structural skeleton around which cells split during mitosis and meiosis.






42. Is the outermost of the three main layers of an embryo.






43. Refers to the birthrate of a population.






44. Inorganic phosphate






45. Contains the chromosomes and is the site of reproduction through mitosis and meiosis.






46. Is found on the stem between nodes.






47. Produces the most ATP molecules - yielding 34 ATPs per glucose molecule.






48. Studied the relationships between traits expressed in parents and offspring and the genes that caused the traits to be expressed.






49. Some energy is lost as heat and becomes unusable.






50. 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.
