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 transfer of electrons.






2. Is a phylum that contains sponges.






3. It secretes saliva which enters the digestive tract and aids the digestive process.






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






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






6. Contains the chromosomes and is the site of reproduction through mitosis and meiosis.






7. Are the organelles where cellular respiration occurs.






8. The pituitary gland.






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






10. Decomposition of living matter for consumption.






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






12. The phyla composed of segmented worms.






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






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






15. Is made of stacked cells connected by sieve plates that allow nutrients to pass from cell to cell. They transport food made in the leaves (by photosynthesis) to the rest of the plant).






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






17. Are membrane-bound organelles that contain digestive enzymes that digest dead or unused material within the cell or materials absorbed by the cell for use.






18. Transparency - polarity - high specific heat - and density (lower density when solid than when liquid.).






19. 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






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






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






22. Covalent bonds






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






25. Carbon - Hydrogen - Oxygen - and Nitrogen






26. Ended with the extinction of the dinosaurs.






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






28. Contains optic lobes - controls sight.






29. Is the waxy protective outer coating of leaves.






30. 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.






31. The vocal cords are found in the larynx.






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






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






34. 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.






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






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






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






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






39. 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.






40. A reaction that adds water to another compound. (2 hydrogens - 1 oxygen).






41. Subsets below the kingdom level






42. Refers to the birthrate of a population.






43. 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






44. Plants that produce flowers as reproductive organs. They have two divisions - monocots and dicots.






45. Small - green - heart-shaped gametophyte plant form of a fern that can make its own food and absorb water and nutrients from the soil






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






47. 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.






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






49. Protein synthesis






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