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. Is disorganized - unravelled - DNA with histones attached.






2. 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.






3. Chlorophyll pigments absorb photons of light - leaving the chlorophyll in a higher energy (excited) state - these then supply energy to reactions that produce ATP from ADP and Pi.






4. Plants and animals obtain usable nitrogen






5. Contain one celled eukaryotes such as algae and protozoa.






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






7. An opportunistic life strategy strategy. Lichens invading a bare rock area after a volcanic eruption is an example.






8. The class composed of birds.






9. Niche






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






11. Super-class of vertebrae including organisms with no jaws.






12. Is found on the stem between nodes.






13. Anabolism






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






15. Are the monomers that form nucleic acids - containing a sugar - phosphate group - and a nitrogenous base.






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






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






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






19. Controls hunger and thirst






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






21. Covalent bonds






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






23. Is the organelle where cellular reproductive processes occur.






24. Covers and protects the leaf.






25. 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.






26. All store energy within their chemical bonds.






27. Controls olfactory lobes (smell)






28. 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.






29. Controls balance and muscle coordination






30. 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.






31. The physical place where a particular organism lives. It must include all the factors that will support its life and reproduction.






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






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






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






35. 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.






36. What phylum are snakes in?






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. 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






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






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






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






42. Develops from the morula as a thin layer of cells surrounding an internal cavity.






43. When the water concentration inside and outside the cell is equal - It is said to be in an...






44. The phyla of sponges.






45. The phyla of round worms.






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






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






48. 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.






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






50. An enzyme is unaffected by the reactions it catalyzes
