Give reasons for the following :
(A) Aquatic species are more comfortable in cold water than warm water.
( b) At higher altitude people suffer anoxia resulting in inability to think.

Explanation

The amount of dissolved ozygen in water decreses with rise in the wather 's temperature Cold water has more has more dissolyed oxygen per unit area than warm water .Thus the resion why aquatic animals are more comfortable in cold water that warm water .
(b) At high altitudes the partial pressure of oxygen less than that at the gruond level. This leads to low oxygen causes climbers to become weak and unable to thnk clearly symptoms of a condition known as anoxia.
