How do camels/polar bears control their body temperature? Give 5 reasons for each..?
1Camels have oval shaped blood cell


2Camels eat vegetation which contain moisture.


3Camels sweat only when it is too hot


4The upper body temperature is often not reached during the day therefore the camel may not sweat all day.


5Evaporation of the sweat takes place at the skin level thereby being ver efficient at cooling the body compared to the amount of water lost through sweating.





1Polar consist of a of a layer of dense underfur and an outer layer of guard hair.


2Polar bears are insulated by there 10cm of blubber.


That's all I can find but I tried.
