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






2. In DNA Guanine pairs with...






3. The large brain and upright posture of Homo Sapiens...






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






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






6. An enzyme is unaffected by the reactions it catalyzes






7. 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.






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






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






10. 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






11. 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.






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






13. Process in which elements - chemical compounds - and other forms of matter are passed from one organism to another and from one part of the biosphere to another.






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






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






16. The pituitary gland.






17. Breaking down






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






19. Is the major component of sand and is the most abundant element found in the lithosphere. It is not recycled.






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






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






22. The vocal cords are found in the larynx.






23. In DNA Thymine pairs with...






24. Includes all living and nonliving components of the Earth to support living things.






25. Is the process that releases energy for use by the cell.






26. Ended with the extinction of the dinosaurs.






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






28. Is found on the stem between nodes.






29. Carbon - Hydrogen - Oxygen - and Nitrogen






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






31. Is a phylum that contains sponges.






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






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






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






35. Respiratory organs within insects






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






37. Secretes insulin to lower blood sugar and maintain equilibrium. A person eats three candy bars. Within minutes this endocrine gland affects blood-glucose homeostasis.






38. Contains multicellular photosynthetic eukaryotic organisms including gymnosperms and angiosperms.






39. Layer that will become the skin - some endocrine glands - and the nervous system.






40. Produce antibodies into the bloodstream that find and attach themselves to foreign antigens (toxins - bacteria).






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






42. An orienting response to light.






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






44. 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.






45. 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.






46. Is a packet of digestive enzymes that destroy cellular wastes.






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






48. A length of DNA (with corresponding histones) is responsible for the production of a certain protein that causes a particular trait to be expressed in an organism.






49. The individual we recognize as an adult fern.






50. 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
