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






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






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






4. Controls olfactory lobes (smell)






5. Fruits that develop from a single ripened ovary (apple - olive - acorn - cucumber).






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






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






8. Niche






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






10. The phyla composed of segmented worms.






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






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






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






14. Nonvascular plants such as mosses which lack tissue for conducting food or water.






15. 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.






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






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






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






19. Controls hunger and thirst






20. Is the control of protein synthesis. Genetic traits are expressed and specialization of cells occur as a result of the combination of proteins produced by the DNA of a cell.






21. 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.






22. Is the sugar that lactase acts upon.






23. Are the organelles where cellular respiration occurs.






24. 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.






25. The vocal cords are found in the larynx.






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






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






28. Is the outermost layer of cells of the stem.






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






30. States that where random mating is occurring within a population that is in equilibrium with its environment - the gene frequencies and genotype ratios will remain constant from generation to generation. It is a mathematical formula that shows why re






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






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






33. 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.






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






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






36. The phyla of sponges.






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






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






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






40. The size of a cell is limited by the ratio of its surface area to volume.






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






42. Internally generated patterns of body functions - including hormonal signals - sleep - blood pressure - and temperature regulation - which have approximately a 24-hour cycle and occur even in the absence of normal cues about whether it is day or nigh






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






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






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






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






47. The most recent and present era. It includes the radiation of flowering plants - the angiosperms.






48. Are surrounded by capillaries that allow for carbon dioxide to diffuse into the lungs and oxygen to diffuse out.






49. An enzyme is unaffected by the reactions it catalyzes






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