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. Sex-linked recessive disorder carried on the x chromosome defined by the absence of one or more proteins required for blood clotting






2. Between the endoderm and ectoderm - layer that will eventually form the muscles - and organs of the skeletal - circulatory - respiratory - reproductive - and excretory systems.






3. Synthesis






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






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






6. Niche






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






8. The size of a cell is limited by the ratio of its surface area to volume.






9. Process of breaking down complex materials (foods) to form simpler substances and release energy.






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






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






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






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






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






15. Has extreme cold temperatures - low precipitation - modified grassland - perma-frost - a short growing season and some plants and animals.






16. 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.






17. Decomposition of living matter for consumption.






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






19. 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.






20. Is weaker than ionic - covalent - disulfide - or double bonds.






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






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






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






24. The sharp boundary of an ecosystem.






25. Inorganic phosphate






26. Covalent bonds






27. The vocal cords are found in the larynx.






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






29. 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.






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






31. 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.






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






33. Is the waxy protective outer coating of leaves.






34. The phyla of round worms.






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






36. The individual we recognize as an adult fern.






37. 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.






38. Subsets below the kingdom level






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






40. 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.






41. The pituitary gland.






42. Carbon - nitrogen - phosphorous - and water. These are all recycled through biogeochemical processes.






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






44. 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).






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






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






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






49. The pharynx is between the nasal passage and the trachea. Air passes into the body via the nasal passage - then passes through the pharynx and on to the trachea.






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