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






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






3. Inorganic phosphate






4. Fruits that develop from a single ripened ovary (apple - olive - acorn - cucumber).






5. 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.






6. Some energy is lost as heat and becomes unusable.






7. 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.






8. A suffix meaning 'to break apart.' O || ||






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






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






11. Is the outermost of the three main layers of an embryo.






12. 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






13. Synthesis






14. The phyla composed of segmented worms.






15. 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.






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






17. Digestive enzymes - hydrochloric acid - and gastric juices which aid in digestion. The mucous secreted by the stomach protects the stomach lining from the acids and juices.






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






19. Produce antibodies into the bloodstream that find and attach themselves to foreign antigens (toxins - bacteria).






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






21. Anabolism






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






23. 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






24. The phyla of round worms.






25. The process of forming eggs and sperm cells in the reproductive organs.






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. Is a kind of plain characterized by a warm climate - grassland - and seasonally dry climate conditions.






28. 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.






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






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






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






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






33. Covers and protects the leaf.






34. 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






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






36. Is a packet of digestive enzymes that destroy cellular wastes.






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






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






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






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






41. Is found on the stem between nodes.






42. The vocal cords are found in the larynx.






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






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






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






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






47. Biotic (living) factors such as population and food source - and abiotic (non-living) factors such as weather - temperature - soil features - sunlight).






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






49. 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.






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