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






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






3. Contains organisms that are multicellular eukaryotes including molds and mushrooms.






4. Is more like branching out of a tree with dead ends and new branches appearing simultaneously than like steps on a ladder.






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






6. Controls olfactory lobes (smell)






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






8. 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.






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






10. Between the endoderm and ectoderm - layer that will eventually form the muscles - and organs of the skeletal - circulatory - respiratory - reproductive - and excretory systems.






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






12. High temperatures






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






14. Is the process that releases energy for use by the cell.






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






16. 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.






17. Synthesis






18. Is the organelle where cellular reproductive processes occur.






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






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






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






22. Is an accidental change of the DNA sequence of the gene that can result in creating a change of trait that is not found in the parent.






23. Are organic cofactors or coenzymes that are required by some enzymatic reactions.






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






25. 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.






26. 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.






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






28. 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.






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






30. 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






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






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






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






34. 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.






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






36. 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.






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






38. An orienting response to light.






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






40. Is found on the stem between nodes.






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






42. Anabolism






43. 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






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






45. Transfers water and does not require sieve plates to allow nutrients through.






46. The effect of a substrate concentration on the initial reaction rate in the presence of a limited amount of enzyme: _________________ as the concentration of substrate is increased until all the enzymes are used - then the reaction rate will level of






47. 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






48. Protein synthesis






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






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