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. Decomposition of living matter for consumption.






2. Controls balance and muscle coordination






3. Is composed of an anterior and posterior lobe. The stalk of the lobe is connected to the hypothalamus. Antidiuretic Hormone (AH) is produced in the hypothalamus and stored in the posterior pituitary. Upon nervous stimulation from the hypothalamus - t






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






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






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






7. Is the number of organisms that can be supported within a particular ecosystem.






8. Is weaker than ionic - covalent - disulfide - or double bonds.






9. 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






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






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






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






13. The phyla composed of segmented worms.






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






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






16. Synthesis






17. The transfer of electrons.






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






19. Provide rigidity to plant cells (and some bacteria) and are not found within animal cells.






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






21. Some energy is lost as heat and becomes unusable.






22. Layer that will become the skin - some endocrine glands - and the nervous system.






23. Covalent bonds






24. 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.






25. Are formed when the plasma membrane of a cell encloses a molecule outside the membrane - then releases a membrane bound sack containing the desired molecule into the cytoplasm. This process allows the cell to absorb molecules that are larger in size






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






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






28. The vocal cords are found in the larynx.






29. Assumes that there are periods of stability during which little evolutionary change occurs - and that speciation can occur rapidly over a very short period of time.






30. Is a kind of plain characterized by a warm climate - grassland - and seasonally dry climate conditions.






31. Secretes insulin to lower blood sugar and maintain equilibrium. A person eats three candy bars. Within minutes this endocrine gland affects blood-glucose homeostasis.






32. Mitochondria - they constitute the center of cellular respiration.

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






34. 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.






35. 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.






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






37. The phylum of insects (bees).






38. What phylum are snakes in?






39. Plants and animals obtain usable nitrogen






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






41. An orienting response to light.






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






43. Is a phylum that contains sponges.






44. Protein synthesis






45. Disease causing






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






47. Respiratory organs within insects






48. 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.






49. 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.






50. Engages in both passive and active transport.
