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






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






3. Disease causing






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






5. The class composed of birds.






6. Is weaker than ionic - covalent - disulfide - or double bonds.






7. In both living and non-living environments.






8. The effect of a substrate concentration on the initial reaction rate in the presence of a limited amount of enzyme: _________________ as the concentration of substrate is increased until all the enzymes are used - then the reaction rate will level of






9. The phylum of insects (bees).






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






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






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






13. Enzymes are usually __________ to certain reactions.






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






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






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






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






18. Contains optic lobes - controls sight.






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






20. Is the waxy protective outer coating of leaves.






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






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






23. The transfer of electrons.






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






25. 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.






26. Produce seeds without flowers. They include conifers (cone-bearers) and cycads.






27. Bacteria break ammonia into nitrites - then into nitrates that are usable by plants; volcanic activity produces ammonia and nitrates that enter the soil and can be absorbed by plants; lightning reacts with atmospheric nitrogen to form nitrates that a






28. In DNA Thymine pairs with...






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






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






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






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






33. Attaches to an enzyme and blocks the enzyme reaction rather than enhancing it - like a prosthetic group would.






34. Controls olfactory lobes (smell)






35. 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.






36. Is an accidental change of the DNA sequence of the gene that can result in creating a change of trait that is not found in the parent.






37. 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






38. Breaking down






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






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






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






42. (of some plants or fungi) feeding on dead or decaying organic matter






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






44. 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






45. Some energy is lost as heat and becomes unusable.






46. All store energy within their chemical bonds.






47. Is found on the stem between nodes.






48. Is comprised of all the organisms that interact within a given ecosystem whether or not it is at carrying capacity.






49. Synthesis






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