A) Aquatic
B) Aerial
C) Marine
D) Esturine
Correct Answer: B
Solution :
Oxygen gas accounts for nearly 21% of the atmosphere and has a partial pressure \[({{P}_{{{O}_{2}}}})\]of 159 mm Hg. At high altitudes, where the atmosphere is less influenced by gravity, partial pressure declines in direct proportion to the decrease in atmospheric pressure. The gases in air have very different solubilities in water. Carbon dioxide is most soluble, whereas \[{{O}_{2}}\] is only \[\frac{1}{20}\] as soluble as \[C{{O}_{2}}\].
