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. 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.






2. Is the waxy protective outer coating of leaves.






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






4. 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.






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






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






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






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






9. Is a phylum that contains jellyfish - hydra - etc.






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






11. Is the earliest period of the Paleozoic era. Began with the Cambrian explosion - this explosion of life resulted in the representatives of most of the modern phyla being present.






12. High temperatures






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






14. The bronchi lead to the two lungs where they branch out in all directions into smaller tubules known as bronchioles.






15. Studied the relationships between traits expressed in parents and offspring and the genes that caused the traits to be expressed.






16. Covers and protects the leaf.






17. Are the organelles where cellular respiration occurs.






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






19. All store energy within their chemical bonds.






20. Anabolism






21. The pituitary gland.






22. 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.






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






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






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






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






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






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






29. Niche






30. The class composed of birds.






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






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






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






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






35. An orienting response to light.






36. Controls hunger and thirst






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






38. 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.






39. Are more closely related to Homo Sapiens than to other apes - but Homo Sapiens did not evolve from chimpanzees.






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






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






42. Decomposition of living matter for consumption.






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






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






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






46. The phyla of sponges.






47. Is found on the stem between nodes.






48. Has extreme cold temperatures - low precipitation - modified grassland - perma-frost - a short growing season and some plants and animals.






49. Contains optic lobes - controls sight.






50. Are cells involved in immunity and are produced in bone marrow as stem cells.
