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 systematic search for individuals with a specific genotype in a delineated population.






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






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






4. 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.






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






6. An orienting response to light.






7. The solid mass of cells resulting from the cleavage of the ovum before the formation of a blastula.






8. 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.






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






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






11. Is the sugar that lactase acts upon.






12. Enzymes are usually __________ to certain reactions.






13. Attaches to an enzyme and blocks the enzyme reaction rather than enhancing it - like a prosthetic group would.






14. Proposes that those individuals within a population that are most adapted to the environment are also the most likely individuals to produce viable offspring.






15. The phyla composed of segmented worms.






16. The phyla of round worms.






17. Is a compound fruit that develops from many ovaries of a single flower fusing together (raspberry).






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






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






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






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






22. Refers to the birthrate of a population.






23. The class composed of birds.






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






25. 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






26. Decomposition of living matter for consumption.






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






28. Disease causing






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






30. Are cells involved in immunity and are produced in bone marrow as stem cells.






31. 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.






32. What phylum are snakes in?






33. Is disorganized - unravelled - DNA with histones attached.






34. In both living and non-living environments.






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






36. The large brain and upright posture of Homo Sapiens...






37. 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






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






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






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






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






42. 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.






43. 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.






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






45. 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.






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






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






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






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






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