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. Respiratory organs within insects






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






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






4. 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






5. Is the sugar that lactase acts upon.






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






7. Develops from the morula as a thin layer of cells surrounding an internal cavity.






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






9. 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






10. Controls hunger and thirst






11. 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).






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






13. The pituitary gland.






14. A type of innate behavior (instinct.) The FAP is a preprogrammed response to a particular stimulus (known as a releaser stimulus). FAP's include courtship behaviors and feeding of young. These are not learned behaviors - they are automatically perfor






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






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






17. Can be accounted for by the theory of punctuated equilibrium. The fossil record shows periods of stability with regard to appearance and disappearance of species as well as periods of sudden change.






18. The sharp boundary of an ecosystem.






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






20. Ended with the extinction of the dinosaurs.






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






22. 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.






23. 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






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






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






26. Occurs when an individual learns not to respond to a particular stimulus - for instance when a stimulus is repeated many times without consequence.






27. Decomposition of living matter for consumption.






28. Process in which elements - chemical compounds - and other forms of matter are passed from one organism to another and from one part of the biosphere to another.






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






30. The phyla composed of segmented worms.






31. Cleave strands of DNA segments at certain sites.






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






33. Is a compound fruit that forms from several ovaries of separate flowers that fuse together during ripening (strawberry - or pineapple).






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






35. 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.






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






37. When the water concentration inside and outside the cell is equal - It is said to be in an...






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






39. Has an equal (50%) chance of being passed from a carrier mother to a son or a daughter.






40. 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.






41. In both living and non-living environments.






42. Covalent bonds






43. Most chemical pollutants accidentally ingested by humans are __________ - mixed with broken down pigments in the bile - then bile is secreted into the small intestine - proceeds to the large intestine - and is expelled in the feces.






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






45. Occurs when an individual from an adjacent population of the same species immigrates and breeds with a member of a previously locally isolated group - resulting in a change in the gene pool.






46. 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.






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






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






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






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