    Ventilation and Oxygen Consumption Results Oxygen Concentration Oxygen concentration in water can be altered by the conditions it is exposed to. For instance cold water has a higher oxygen concentration than warm water. In our experiment we were able to observe the change in oxygen concentration of water at two different temperatures (15C and 25C) with a fish in each environment. Our results proved that the starting oxygen concentration of the cold water was higher than that of warm water. It also showed

    Oxygen Exchange and Transport Oxygen exchange or respiration takes place at a respiratory surface; a boundary between the external environment and the interior of the body. Gas exchange is the process by which oxygen and carbon dioxide (the respiratory gases) move in opposite directions across an organism’s respiratory membranes‚ between the air or water of the external environment and the body fluids of the internal environment. Oxygen is needed by cells to extract energy from organic molecules

    Oxygen Requirements of Bacteria BACKGROUND  The GasPak system is useful for culturing anaerobic bacteria on standard microbiological media because the GasPak generates carbon dioxide and hydrogen. The hydrogen will combine with oxygen present in an anaerobic jar to produce water. This system can reproducibly attain oxygen levels in the parts per million range if used correctly. This is the best method for determining the oxygen requirements of unknown organisms.  A candle jar is useful

    10.19.2011 TITLE: The Importance of Oxygen for Life PURPOSE: To determine whether test tubes filled with bacteria‚ a few salts‚ distilled water‚ and glucose would grow in the presence or absence of oxygen. By adding oxygen to certain tubes and withholding it from other tubes‚ one can determine which bacteria grow the most efficiently. HYPOTHESIS: The test tubes of bacteria with oxygen will grow and thrive over the test tubes without oxygen. METHODS: Using the data shown in Table 7-A-1
