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. Absorb a photon of light and is found in the grana of the chloroplast.






2. Protein synthesis






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






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






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






6. 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.






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






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






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






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






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






12. Carbon - Hydrogen - Oxygen - and Nitrogen






13. Is a substance that changes the speed of a reaction without being affected itself.






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






15. Contain one celled eukaryotes such as algae and protozoa.






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






17. Controls olfactory lobes (smell)






18. 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).






19. High temperatures






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






21. 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.






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






23. Some patrol the blood for antigens - but are also equipped to destroy antigens. They may regulate immune responses as well.






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






25. The individual we recognize as an adult fern.






26. In both living and non-living environments.






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






28. An enzyme is unaffected by the reactions it catalyzes






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






30. Contains optic lobes - controls sight.






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






32. 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.






33. Is a social behavior of an organism that is beneficial to the group at the individual's expense.






34. Is found on the stem between nodes.






35. An orienting response to light.






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






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






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






39. The trachea includes the windpipe or larynx in its upper portion - and the glottis - an opening that allows the gases to pass into the two branches known as the bronchi.






40. Bacteria break ammonia into nitrites - then into nitrates that are usable by plants; volcanic activity produces ammonia and nitrates that enter the soil and can be absorbed by plants; lightning reacts with atmospheric nitrogen to form nitrates that a






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






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






43. The transfer of electrons.






44. Is secreted by the adrenal cortex to promote sodium reabsorption in the kidney.






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






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






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






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






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






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