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. Channels is cell membranes that carry water between cells.






3. Chlorophyll pigments absorb photons of light - leaving the chlorophyll in a higher energy (excited) state - these then supply energy to reactions that produce ATP from ADP and Pi.






4. Is found on the stem between nodes.






5. Super-class of vertebrae including organisms with jaws.






6. Is a special protein that acts as a catalyst for organic reactions.






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






8. Decomposition of living matter for consumption.






9. Protein synthesis






10. The phyla of sponges.






11. This is a carboxyl group and is the signature group found within organic acids.






12. The total amount of genetic information available for a given species.






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






14. Is the waxy protective outer coating of leaves.






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






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






17. Subsets below the kingdom level






18. 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.






19. 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






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






21. Must be present for photosynthesis to occur - it is not used up in the process.






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






23. Inorganic phosphate






24. The destruction of gametes - (sex cells such as sperm and eggs).






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






26. 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).






27. Covers and protects the leaf.






28. Carbon - Hydrogen - Oxygen - and Nitrogen






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






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






31. The process whereby cells build molecules and store energy (in the form of covalent chemical bonds).






32. Plants that produce flowers as reproductive organs. They have two divisions - monocots and dicots.






33. 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.






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






35. Is made of stacked cells connected by sieve plates that allow nutrients to pass from cell to cell. They transport food made in the leaves (by photosynthesis) to the rest of the plant).






36. The class composed of birds.






37. The number of organisms in a given community - can be above or below the carrying capacity.






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






39. 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.






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






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






42. Is the sugar that lactase acts upon.






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






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






45. Cleave strands of DNA segments at certain sites.






46. 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.






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






48. Controls balance and muscle coordination






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






50. In both living and non-living environments.
