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






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






3. The phyla composed of segmented worms.






4. 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.






5. 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.






6. Channels is cell membranes that carry water between cells.






7. An orienting response to light.






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






9. Covalent bonds






10. The individual we recognize as an adult fern.






11. 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.






12. 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.






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






14. The pituitary gland.






15. Are produced when water passes through the cell membrane by osmosis from an area of higher concentration to an area of lower concentration - to equalize water concentration.






16. 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.






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






18. 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.






19. 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.






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






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






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. Provide rigidity to plant cells (and some bacteria) and are not found within animal cells.






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






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






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






27. Mass extinctions promote diversification because _______________ - making conditions favorable for the establishment of new - diverse species.






28. 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






29. Is a kingdom that includes algae and protozoa.






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






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






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






33. The vocal cords are found in the larynx.






34. Where protein synthesis occurs. They float unattached in the cytoplasm. They contain RNA that is specific to their function in protein formation.






35. Digestive enzymes - hydrochloric acid - and gastric juices which aid in digestion. The mucous secreted by the stomach protects the stomach lining from the acids and juices.






36. Is a molecule that stores information for protein synthesis and genetic coding.






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






38. An enzyme is unaffected by the reactions it catalyzes






39. 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).






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






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






42. Niche






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






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






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






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






47. Refers to the birthrate of a population.






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






49. Carbon - Hydrogen - Oxygen - and Nitrogen






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