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 vocal cords are found in the larynx.






2. Ended with the extinction of the dinosaurs.






3. Algae and Protozoa belong to the kingdom...






4. 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.






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






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






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






8. Carbon - Hydrogen - Oxygen - and Nitrogen






9. Covers and protects the leaf.






10. 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.






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






12. Is the sugar that lactase acts upon.






13. A length of DNA (with corresponding histones) is responsible for the production of a certain protein that causes a particular trait to be expressed in an organism.






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






15. Controls hunger and thirst






16. 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






17. 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.






18. The class composed of birds.






19. Are tubes constructed of a geometrical arrangement of microtubules in a pinwheel shape. Their function includes the formation of new microtubules - but is primarily to form the structural skeleton around which cells split during mitosis and meiosis.






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






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






22. Plants and animals obtain usable nitrogen






23. 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.






24. The process whereby cells build molecules and store energy (in the form of covalent chemical bonds).






25. Is a protein - which is a polymer of amino acids. They generally have the suffix -ase- like lactase.






26. The number of organisms in a given community - can be above or below the carrying capacity.






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






28. 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.






29. Contains optic lobes - controls sight.






30. The bronchi lead to the two lungs where they branch out in all directions into smaller tubules known as bronchioles.






31. Protein synthesis






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






33. Refers to the birthrate of a population.






34. Disease causing






35. 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






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






37. A sex-linked recessive disorder carried on the x chromosome in which an individual cannot perceive certain colors.






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






39. Is composed of a double layer (bilayer) of phospholipids with protein globules imbedded within the layers. The construction of the membrane allows it to aid the function of the cell by permitting entrance and exit of molecules as needed by the cell.






40. The sharp boundary of an ecosystem.






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






42. Subsets below the kingdom level






43. The phylum of insects (bees).






44. States that where random mating is occurring within a population that is in equilibrium with its environment - the gene frequencies and genotype ratios will remain constant from generation to generation. It is a mathematical formula that shows why re






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






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






47. 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.






48. 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.






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






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