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. Contains optic lobes - controls sight.






2. Proposes that those individuals within a population that are most adapted to the environment are also the most likely individuals to produce viable offspring.






3. Ended with the extinction of the dinosaurs.






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






5. Is disorganized - unravelled - DNA with histones attached.






6. Is a disease caused by lack of vitamin C in which the body is unable to build enough collagen (a major component of connective tissue).






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






8. Becomes available for erosion as undersea sedimentary rocks are up-thrust by volcanic activity - erosion releases it from rocks into streams where it combines with oxygen to form phosphates in lakes that are then absorbed by plants - it is recycled t






9. Most chemical pollutants accidentally ingested by humans are __________ - mixed with broken down pigments in the bile - then bile is secreted into the small intestine - proceeds to the large intestine - and is expelled in the feces.






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






11. Nonvascular plants such as mosses which lack tissue for conducting food or water.






12. Can be accounted for by the theory of punctuated equilibrium. The fossil record shows periods of stability with regard to appearance and disappearance of species as well as periods of sudden change.






13. 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






14. Are easily converted to ATP - but the main energy products of the Krebs cycle liberate electrons then used in the electron transfer reactions.






15. Disease causing






16. A type of innate behavior (instinct.) The FAP is a preprogrammed response to a particular stimulus (known as a releaser stimulus). FAP's include courtship behaviors and feeding of young. These are not learned behaviors - they are automatically perfor






17. Developed by the German scientists Schleiden and Schwann - States that all living things are made of cells - cells are the basic units of life - all cells come from pre-existing cells.






18. This is a carboxyl group and is the signature group found within organic acids.






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






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






21. Is the organelle where cellular reproductive processes occur.






22. Are formed when the plasma membrane of a cell encloses a molecule outside the membrane - then releases a membrane bound sack containing the desired molecule into the cytoplasm. This process allows the cell to absorb molecules that are larger in size






23. Respiratory organs within insects






24. The pituitary gland.






25. Protein synthesis






26. Controls olfactory lobes (smell)






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






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






29. The size of a cell is limited by the ratio of its surface area to volume.






30. Is an abundant element found in protoplasm. Together with oxygen - hydrogen - and nitrogen - it composes over 90% of cellular structure.






31. Is a substance that changes the speed of a reaction without being affected itself.






32. Fruits that develop from a single ripened ovary (apple - olive - acorn - cucumber).






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






34. Refers to the birthrate of a population.






35. Develops from the morula as a thin layer of cells surrounding an internal cavity.






36. The vocal cords are found in the larynx.






37. Covalent bonds






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






39. 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.






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






41. 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






42. 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.






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






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. Synthesis






46. 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.






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






48. Stood upright before there was an increase in brain size.






49. What phylum are snakes in?






50. Is a molecule that stores information for protein synthesis and genetic coding.
