Give reasons for the following :
(a) Aquatic species are more comfortable in cold water than warm water.
(b) At higher altitudes people suffer from anoxia resulting in inability to think.
(a) Aquatic species are more comfortable in cold nature than warm. since, availibility of dissolved in air is more as decrease in temperature, increases in solubility of gases.
(b) At higher altitudes people suffer from anoxia resulting in mobillity to think as they suffer from low concentration of oxygen in blood since at higher altitudes the pressure of air is less which makes them weak.
