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






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






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






4. Stood upright before there was an increase in brain size.






5. 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






6. Engages in both passive and active transport.






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

8. 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






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






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






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






12. 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.






13. 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.






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






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






16. Is an abundant element found in protoplasm. Together with oxygen - hydrogen - and nitrogen - it composes over 90% of cellular structure.






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






18. 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.






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






20. 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






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






22. Is the control of protein synthesis. Genetic traits are expressed and specialization of cells occur as a result of the combination of proteins produced by the DNA of a cell.






23. Covers and protects the leaf.






24. Fruits that develop from a single ripened ovary (apple - olive - acorn - cucumber).






25. High temperatures






26. Is a kingdom that includes algae and protozoa.






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






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






29. What phylum are snakes in?






30. Fossilized burrows from multicellular organisms begin to appear in the geological record approximately 700 million years ago during the Precambrian period. These multicellular animals had only soft parts and could not be fossilized.






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






32. Is found on the stem between nodes.






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






34. Are the monomers that form nucleic acids - containing a sugar - phosphate group - and a nitrogenous base.






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






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






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






38. Contains optic lobes - controls sight.






39. Ended with the extinction of the dinosaurs.






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






41. Plants and animals obtain usable nitrogen






42. 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.






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






44. Are produced when water passes through the cell membrane by osmosis from an area of higher concentration to an area of lower concentration - to equalize water concentration.






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






46. Covalent bonds






47. Is a phylum that contains sponges.






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






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






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