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






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






3. Is found in the root cap and is responsible for quick growth in the roots.






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






5. 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






6. What phylum are snakes in?






7. 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






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






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






10. Inorganic phosphate






11. 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






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






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






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






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






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






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






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






19. 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.






20. Anabolism






21. Has an equal (50%) chance of being passed from a carrier mother to a son or a daughter.






22. 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






23. High temperatures






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






25. 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.






26. Mitochondria - they constitute the center of cellular respiration.

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






28. Carbon - Hydrogen - Oxygen - and Nitrogen






29. Controls olfactory lobes (smell)






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






31. Is found on the stem between nodes.






32. Attaches to an enzyme and blocks the enzyme reaction rather than enhancing it - like a prosthetic group would.






33. May be ions or non-protein molecules - they are similar to cofactors - but differ in that they are tightly attached by covalent bonds to the enzyme - rather than being separate atoms or molecules.






34. 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






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






36. The phyla of round worms.






37. Is the period when the cell is active in carrying on the function it was designed to perform within the organism. Cells spend much more time in interphase than in cell division.






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






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






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






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






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






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






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






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






46. Nonvascular plants such as mosses which lack tissue for conducting food or water.






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






48. The transfer of electrons.






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






50. Are the organelles where cellular respiration occurs.
