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. Is a substance that changes the speed of a reaction without being affected itself.






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






3. The phylum of insects (bees).






4. 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






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






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






8. Plants and animals obtain usable nitrogen






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






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






11. 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






12. The process of forming eggs and sperm cells in the reproductive organs.






13. 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






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






15. Is a coenzyme required in the synthesis of collagen.






16. Contains optic lobes - controls sight.






17. Are the organelles where cellular respiration occurs.






18. The phyla composed of segmented worms.






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






20. Is found on the stem between nodes.






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






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






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






24. 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.






25. Controls balance and muscle coordination






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






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






28. A hydrogen bond involves the ________________ and can be easily broken.






29. The individual we recognize as an adult fern.






30. Is the sugar that lactase acts upon.






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






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






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






34. Protein synthesis






35. Are tubes constructed of a geometrical arrangement of microtubules in a pinwheel shape. Their function includes the formation of new microtubules - but is primarily to form the structural skeleton around which cells split during mitosis and meiosis.






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






37. 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






38. Between the endoderm and ectoderm - layer that will eventually form the muscles - and organs of the skeletal - circulatory - respiratory - reproductive - and excretory systems.






39. 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






40. Niche






41. Inorganic phosphate






42. 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).






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






44. The destruction of gametes - (sex cells such as sperm and eggs).






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






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






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






48. Covers and protects the leaf.






49. When stems bend toward the light it is due to _____________ the hormone auxin - in response to light - migrates from the light to the dark side of the shoot tip. The cells on the dark side now contain more auxin - which causes the cells on that side






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