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. 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.






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






3. Niche






4. Subsets below the kingdom level






5. 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.






6. Is the process that releases energy for use by the cell.






7. In DNA Guanine pairs with...






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






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






10. The large brain and upright posture of Homo Sapiens...






11. Controls sensory and motor responses - and controls memory - speech - and intelligence factors.






12. Is a social behavior of an organism that is beneficial to the group at the individual's expense.






13. Is a disease caused by lack of vitamin C in which the body is unable to build enough collagen (a major component of connective tissue).






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






15. Covalent bonds






16. The individual we recognize as an adult fern.






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






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






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






20. The role played by an organism in its food chain.






21. 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).






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






23. Layer that will become the gut lining as well as some accessory structures.






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






25. Is the outermost of the three main layers of an embryo.






26. The phylum of insects (bees).






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






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






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






30. Are more closely related to Homo Sapiens than to other apes - but Homo Sapiens did not evolve from chimpanzees.






31. Most fossils of Hominids are from continents other than...






32. 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.






33. Cleave strands of DNA segments at certain sites.






34. The phyla of round worms.






35. The pituitary gland.






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






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






38. Some energy is lost as heat and becomes unusable.






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






40. 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






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






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






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






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






45. Is the major component of sand and is the most abundant element found in the lithosphere. It is not recycled.






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






47. Is found on the stem between nodes.






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






49. Is a compound fruit that develops from many ovaries of a single flower fusing together (raspberry).






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