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 sharp boundary of an ecosystem.






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






3. Some enzymes contain a __________ component that is essential to their functions.






4. An enzyme is unaffected by the reactions it catalyzes






5. The vocal cords are found in the larynx.






6. 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.






7. Is found on the stem between nodes.






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






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






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






11. Niche






12. There was extensive radiation of fish during the Devonian and Silurian periods within the Paleozoic Era.






13. 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






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






15. Are surrounded by capillaries that allow for carbon dioxide to diffuse into the lungs and oxygen to diffuse out.






16. The systematic search for individuals with a specific genotype in a delineated population.






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






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






19. Plants and animals obtain usable nitrogen






20. Algae and Protozoa belong to the kingdom...






21. Are the monomers that form nucleic acids - containing a sugar - phosphate group - and a nitrogenous base.






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






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






24. Process of breaking down complex materials (foods) to form simpler substances and release energy.






25. 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.






26. 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.






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






28. 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.






29. Internally generated patterns of body functions - including hormonal signals - sleep - blood pressure - and temperature regulation - which have approximately a 24-hour cycle and occur even in the absence of normal cues about whether it is day or nigh






30. All store energy within their chemical bonds.






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






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






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






34. Subsets below the kingdom level






35. When the water concentration inside and outside the cell is equal - It is said to be in an...






36. Most fossils of Hominids are from continents other than...






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






38. Developed by the German scientists Schleiden and Schwann - States that all living things are made of cells - cells are the basic units of life - all cells come from pre-existing cells.






39. Is the waxy protective outer coating of leaves.






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






41. Is the organelle where cellular reproductive processes occur.






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






43. 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.






44. The pharynx is between the nasal passage and the trachea. Air passes into the body via the nasal passage - then passes through the pharynx and on to the trachea.






45. Is a protein - which is a polymer of amino acids. They generally have the suffix -ase- like lactase.






46. Enzymes are usually __________ to certain reactions.






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






48. Veins in the leaf and are also distributed throughout the stem






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






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