Ans . It is general belief that a CHAMELEON changes its colour as a form of defence , by blending with the surroundings and thus hide from the enemy.This is not true.Actually it does not take the advantage of this form of disguise to hide from enemies. The colour changes are a result of the sun's rays on the skin, and the effect of its nerves when stimulated by anger or fear.

Q . How do spiders spin their webs ?
Ans . The spiders web are made of fine silk thread. The spider has certain glands in its belly or abdomen which produce the silk as a liquid .

On the contrary a man made rocket or space shuttle is protected by a thick heat shield which can withstand very high temperatures and thus they do not burn. This shield is made of heat resistant tiles. If there were no shield, the rocket or the space shuttle would burn up, just like a meteor .
