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






2. Channels is cell membranes that carry water between cells.






3. 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.






4. Produce seeds without flowers. They include conifers (cone-bearers) and cycads.






5. Veins in the leaf and are also distributed throughout the stem






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






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






8. 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.






9. 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.






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






11. The individual we recognize as an adult fern.






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






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






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






15. 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.






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






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






19. Is a kingdom that includes algae and protozoa.






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






21. Synthesis






22. Is found on the stem between nodes.






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






24. Is the period when the cell is active in carrying on the function it was designed to perform within the organism. Cells spend much more time in interphase than in cell division.






25. Covalent bonds






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






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






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






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






30. Refers to the birthrate of a population.






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






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






33. Engages in both passive and active transport.






34. Controls olfactory lobes (smell)






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






36. Cleave strands of DNA segments at certain sites.






37. Respiratory organs within insects






38. 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.






39. Is comprised of all the organisms that interact within a given ecosystem whether or not it is at carrying capacity.






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






41. Produces the most ATP molecules - yielding 34 ATPs per glucose molecule.






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. Algae and Protozoa belong to the kingdom...






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






45. 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.






46. 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).






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






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






49. 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.






50. The phyla of round worms.
