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 organisms that are multicellular eukaryotes including molds and mushrooms.






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






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






4. A hydrogen bond involves the ________________ and can be easily broken.






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






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






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






8. Protein synthesis






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






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






11. 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.






12. In DNA Thymine pairs with...






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






14. Is more like branching out of a tree with dead ends and new branches appearing simultaneously than like steps on a ladder.






15. It secretes saliva which enters the digestive tract and aids the digestive process.






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






17. 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.






18. Are organic cofactors or coenzymes that are required by some enzymatic reactions.






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






20. Controls balance and muscle coordination






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






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






23. 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.






24. Carbon - Hydrogen - Oxygen - and Nitrogen






25. Is the organelle where cellular reproductive processes occur.






26. Occurs when an individual learns not to respond to a particular stimulus - for instance when a stimulus is repeated many times without consequence.






27. In DNA Guanine pairs with...






28. Inorganic phosphate






29. Occurs when an individual from an adjacent population of the same species immigrates and breeds with a member of a previously locally isolated group - resulting in a change in the gene pool.






30. Consists of undifferentiated cells capable of quick growth and specialization. It is responsible for elongation of the stem.






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






32. Is a kingdom that includes algae and protozoa.






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






34. 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.






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






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






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






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






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






40. In both living and non-living environments.






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






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






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






44. Is secreted by the adrenal cortex to promote sodium reabsorption in the kidney.






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






46. Absorb a photon of light and is found in the grana of the chloroplast.






47. Is the number of organisms that can be supported within a particular ecosystem.






48. Covalent bonds






49. Controls olfactory lobes (smell)






50. Niche
