(i) Desert animals have evolved different adaptations to cope up with the extreme desert heat.
Some of them hide themselves under the ground while some eat food laden with moisture.
Thus, desert animals survive without water.
(ii) Mongoose are more active than snakes.
When a mongoose and snake fight, the mongoose tries to escape from the attack of the snake and the snake keeps attacking on the mongoose.
The snake gets tired and gets killed by mongoose.

When there is no water, the fat globules inside the hump break down and release water.
Thus camels can survive for a longer time without water.
