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






2. A reaction that adds water to another compound. (2 hydrogens - 1 oxygen).






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






4. Plants and animals obtain usable nitrogen






5. The phyla of round worms.






6. Is composed of an anterior and posterior lobe. The stalk of the lobe is connected to the hypothalamus. Antidiuretic Hormone (AH) is produced in the hypothalamus and stored in the posterior pituitary. Upon nervous stimulation from the hypothalamus - t






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






8. Develops from the morula as a thin layer of cells surrounding an internal cavity.






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






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






11. 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.






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






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






14. An orienting response to light.






15. Is when expression of genetic traits is determined by weather the trait is inherited from the mother or the father.






16. 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






17. Inorganic phosphate






18. Must be present for photosynthesis to occur - it is not used up in the process.






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






20. Carbon - Hydrogen - Oxygen - and Nitrogen






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






22. 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






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






24. In DNA Guanine pairs with...






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






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






27. Contains the chromosomes and is the site of reproduction through mitosis and meiosis.






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






29. Controls hunger and thirst






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






31. Occurs when an individual from an adjacent population of the same species immigrates and breeds with a member of a previously locally isolated group - resulting in a change in the gene pool.






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






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






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






35. The pituitary gland.






36. Is the outermost layer of cells of the stem.






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






38. 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.






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






40. The transfer of electrons.






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






42. 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.






43. The individual we recognize as an adult fern.






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






45. The phyla composed of segmented worms.






46. Engages in both passive and active transport.






47. What phylum are snakes in?






48. 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.






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






50. The cells of a developing embryo (at the gastrula stage) differentiate into layers - that will later develop into different tissues and organs - including the mesoderm - ectoderm - and endoderm.
