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






2. Inorganic phosphate






3. 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.






4. Is the sugar that lactase acts upon.






5. The phyla of round worms.






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






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






8. What phylum are snakes in?






9. Disease causing






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






11. Carbon - nitrogen - phosphorous - and water. These are all recycled through biogeochemical processes.






12. An enzyme is unaffected by the reactions it catalyzes






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






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






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






16. 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.






17. The part of the earth that contains all living things - including the atmosphere (air) - the lithosphere (earth) - and the hydrosphere (water).






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






19. Is found on the stem between nodes.






20. 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.






21. High temperatures






22. Is a kingdom that includes algae and protozoa.






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






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






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






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






27. Produce adrenaline. This hormone is a well-known constrictor of blood vessels.






28. Biotic (living) factors such as population and food source - and abiotic (non-living) factors such as weather - temperature - soil features - sunlight).






29. 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.






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






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






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






33. A reaction that adds water to another compound. (2 hydrogens - 1 oxygen).






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






35. Are tubes constructed of a geometrical arrangement of microtubules in a pinwheel shape. Their function includes the formation of new microtubules - but is primarily to form the structural skeleton around which cells split during mitosis and meiosis.






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






37. 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.






38. 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






39. Covers and protects the leaf.






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






41. Contains optic lobes - controls sight.






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






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






44. Carbon - Hydrogen - Oxygen - and Nitrogen






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






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






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






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






49. Fossilized burrows from multicellular organisms begin to appear in the geological record approximately 700 million years ago during the Precambrian period. These multicellular animals had only soft parts and could not be fossilized.






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