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






2. Is a phylum that contains sponges.






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






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






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






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






7. Has an equal (50%) chance of being passed from a carrier mother to a son or a daughter.






8. The process of forming eggs and sperm cells in the reproductive organs.






9. 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.






10. 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.






11. An opportunistic life strategy strategy. Lichens invading a bare rock area after a volcanic eruption is an example.






12. The individual we recognize as an adult fern.






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






14. The most recent and present era. It includes the radiation of flowering plants - the angiosperms.






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






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






17. 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).






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






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






20. What phylum are snakes in?






21. Contain organisms that are multicellular eukaryotes including vertebrates and invertebrates.






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






23. 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






24. Fossilized burrows from multicellular organisms begin to appear in the geological record approximately 700 million years ago during the Precambrian period. These multicellular animals had only soft parts and could not be fossilized.






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






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






27. 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.






28. Is the organelle where cellular reproductive processes occur.






29. Transparency - polarity - high specific heat - and density (lower density when solid than when liquid.).






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






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






32. The sharp boundary of an ecosystem.






33. Must be present for photosynthesis to occur - it is not used up in the process.






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


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






36. Is found in the root cap and is responsible for quick growth in the roots.






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






38. 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.






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






40. Are the organelles where cellular respiration occurs.






41. Occurs when two populations are geographically isolated from each other. Over time this results in the production of two separate species.






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






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






44. Niche






45. Has extreme hot or cold temperatures - with very low precipitation - sandy or rocky terrain - sparse vegetation (mainly succulents) - small animals - rodents - and reptiles.






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






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






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






49. 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.






50. Between the endoderm and ectoderm - layer that will eventually form the muscles - and organs of the skeletal - circulatory - respiratory - reproductive - and excretory systems.
