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






3. 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.






4. Energy transformations that occur as chemicals are broken down or synthesized within the cell.






5. Plants and animals obtain usable nitrogen






6. Becomes available for erosion as undersea sedimentary rocks are up-thrust by volcanic activity - erosion releases it from rocks into streams where it combines with oxygen to form phosphates in lakes that are then absorbed by plants - it is recycled t






7. The phyla of round worms.






8. All store energy within their chemical bonds.






9. 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.






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






11. 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






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






13. Is the organelle where cellular reproductive processes occur.






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






15. The individual we recognize as an adult fern.






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






17. Breaking down






18. 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






19. Controls balance and muscle coordination






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






21. The pituitary gland.






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. 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






24. The sharp boundary of an ecosystem.






25. Controls hunger and thirst






26. Ended with the extinction of the dinosaurs.






27. Respiratory organs within insects






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






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






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






31. Contains optic lobes - controls sight.






32. 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






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






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






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






36. Controls olfactory lobes (smell)






37. 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.






38. Stood upright before there was an increase in brain size.






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






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






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






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






43. Contains many genes and is a structure comprised of linear DNA and associated proteins.






44. The trachea includes the windpipe or larynx in its upper portion - and the glottis - an opening that allows the gases to pass into the two branches known as the bronchi.






45. 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.






46. The phyla composed of segmented worms.






47. Niche






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






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