1) Kangaroo rat never drinks Water.

Reason :

• The kangaroo rat is almost perfectly adapted to life in the desert.

• They can survive without ever drinking any water, getting needed moisture from their seed diet.

2) How does Polar bear survive in extreme arctic cold?

Reason :

• Polar bears live in one of the planet's coldest environments and depend on a thick coat of insulated fur, which covers a warming layer of fat.

• Fur even grows on the bottom of their paws, which protects against cold surfaces and provides a good grip on ice.

3) What is a hissing cockroach ?

Reason :

• The Madagascar hissing cockroach, also known as the hissing cockroach or simply hisser, is one of the largest species of cockroach, reaching 5 to 7.5 centimetres at maturity.

• They are native to the island of Madagascar, which is off the African mainland, where they are known to be found inside of rotting logs.

4) Why And How Do Spider Spin Webs?

Reason :

• Spiders spin webs to protect their eggs or as a hunting tool, a small silk net that they throw over their prey.

• They can also use webs for transport, climbing to a high point and then release one or more sail-like strands of silk which get caught by the breeze and carries them away.

5) Why Do Snakes Move In Zig Zag Manner ?

Reason :

• Snakes have no legs but they show fast movement in a zigzag manner.

• The movement is carred out by alternating contraction and relaxation of a set of muscles present on the sides of the body creating series of curbves.

• The wave-like motion pushes the body forward by prassing against the ground.
