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. Are the organelles where cellular respiration occurs.






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






3. Is a compound fruit that develops from many ovaries of a single flower fusing together (raspberry).






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






5. 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.






6. The role played by an organism in its food chain.






7. 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.






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






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






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






11. The individual we recognize as an adult fern.






12. A cell will only remain stable if the surface area of the plasma membrane maintains a __________ with the volume of the cytoplasm.






13. Niche






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






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






16. Is a special protein that acts as a catalyst for organic reactions.






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

18. 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.






19. The part of the earth that contains all living things - including the atmosphere (air) - the lithosphere (earth) - and the hydrosphere (water).






20. Engages in both passive and active transport.






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






22. 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.






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






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






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






26. Is the outermost layer of cells of the stem.






27. An orienting response to light.






28. The phyla composed of segmented worms.






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






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






31. Layer that will become the gut lining as well as some accessory structures.






32. 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






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






34. Is the waxy protective outer coating of leaves.






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






36. There was extensive radiation of fish during the Devonian and Silurian periods within the Paleozoic Era.






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






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






39. Controls olfactory lobes (smell)






40. 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.






41. In DNA Guanine pairs with...






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






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






44. Most fossils of Hominids are from continents other than...






45. Covalent bonds






46. In both living and non-living environments.






47. Controls sensory and motor responses - and controls memory - speech - and intelligence factors.






48. Decomposition of living matter for consumption.






49. 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.






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