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. 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.






2. 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






3. 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.






4. Are the organelles where cellular respiration occurs.






5. When stems bend toward the light it is due to _____________ the hormone auxin - in response to light - migrates from the light to the dark side of the shoot tip. The cells on the dark side now contain more auxin - which causes the cells on that side






6. Anabolism






7. Occurs when two populations are geographically isolated from each other. Over time this results in the production of two separate species.






8. 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.






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






10. The destruction of gametes - (sex cells such as sperm and eggs).






11. An orienting response to light.






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






13. May be ions or non-protein molecules - they are similar to cofactors - but differ in that they are tightly attached by covalent bonds to the enzyme - rather than being separate atoms or molecules.






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






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






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






17. The phyla of sponges.






18. 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.






19. Synthesis






20. Is very rare and is not absorbed by plant leaves. Phosphorous is nearly always found in solid form.






21. 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






22. In both living and non-living environments.






23. Protein synthesis






24. All store energy within their chemical bonds.






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






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






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






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






29. Ended with the extinction of the dinosaurs.






30. An enzyme is unaffected by the reactions it catalyzes






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






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






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






34. Is a kingdom that includes algae and protozoa.






35. Is found in the root cap and is responsible for quick growth in the roots.






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






37. Where protein synthesis occurs. They float unattached in the cytoplasm. They contain RNA that is specific to their function in protein formation.






38. Controls balance and muscle coordination






39. Inorganic phosphate






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






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






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






43. Breaking down






44. Has extreme cold temperatures - low precipitation - modified grassland - perma-frost - a short growing season and some plants and animals.






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






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






47. 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.






48. 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.






49. Contains the chromosomes and is the site of reproduction through mitosis and meiosis.






50. In DNA Guanine pairs with...
