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






2. Bacteria break ammonia into nitrites - then into nitrates that are usable by plants; volcanic activity produces ammonia and nitrates that enter the soil and can be absorbed by plants; lightning reacts with atmospheric nitrogen to form nitrates that a






3. The individual we recognize as an adult fern.






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






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






6. 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.






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






8. Is a kind of plain characterized by a warm climate - grassland - and seasonally dry climate conditions.






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






10. The phyla composed of segmented worms.






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






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






13. The solid mass of cells resulting from the cleavage of the ovum before the formation of a blastula.






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






15. 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.






16. Are the organelles where cellular respiration occurs.






17. Are where the sugars synthesized by photosynthesis travel through to various parts of the plant.






18. Are easily converted to ATP - but the main energy products of the Krebs cycle liberate electrons then used in the electron transfer reactions.






19. 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






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






21. Are formed when the plasma membrane of a cell encloses a molecule outside the membrane - then releases a membrane bound sack containing the desired molecule into the cytoplasm. This process allows the cell to absorb molecules that are larger in size






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






23. 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.






24. Subsets below the kingdom level






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






26. Biotic (living) factors such as population and food source - and abiotic (non-living) factors such as weather - temperature - soil features - sunlight).






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






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






29. Some patrol the blood for antigens - but are also equipped to destroy antigens. They may regulate immune responses as well.






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






31. 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.






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






33. The class composed of birds.






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






35. Transfers water and does not require sieve plates to allow nutrients through.






36. Protein synthesis






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






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






39. Is more like branching out of a tree with dead ends and new branches appearing simultaneously than like steps on a ladder.






40. What phylum are snakes in?






41. Covalent bonds






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






43. Is found on the stem between nodes.






44. The lineage that led to the modern Homo Sapiens diverged from the lineage that led to the modern chimpanzee.






45. 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.






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






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






48. Refers to the birthrate of a population.






49. Has extreme hot or cold temperatures - with very low precipitation - sandy or rocky terrain - sparse vegetation (mainly succulents) - small animals - rodents - and reptiles.






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