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






3. Include: Vascular tissue - including both xylem and phloem - and sieve plates existing between cells of the stem.






4. The phylum of insects (bees).






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






6. Anabolism






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






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






9. Subsets below the kingdom level






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






11. 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.






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






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






14. What phylum are snakes in?






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






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






17. Internally generated patterns of body functions - including hormonal signals - sleep - blood pressure - and temperature regulation - which have approximately a 24-hour cycle and occur even in the absence of normal cues about whether it is day or nigh






18. Are organic cofactors or coenzymes that are required by some enzymatic reactions.






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






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






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






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






23. Niche






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






25. The phyla composed of segmented worms.






26. (of some plants or fungi) feeding on dead or decaying organic matter






27. 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






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






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






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






31. Enzymes are usually __________ to certain reactions.






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






33. Controls balance and muscle coordination






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






35. 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.






36. 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.






37. Veins in the leaf and are also distributed throughout the stem






38. Refers to the birthrate of a population.






39. Is found on the stem between nodes.






40. Are cells involved in immunity and are produced in bone marrow as stem cells.






41. Covalent bonds






42. Inorganic phosphate






43. 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.






44. Most chemical pollutants accidentally ingested by humans are __________ - mixed with broken down pigments in the bile - then bile is secreted into the small intestine - proceeds to the large intestine - and is expelled in the feces.






45. 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






46. Respiratory organs within insects






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






48. Protein synthesis






49. 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.






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