Mangoose are immune to the snake venom. It is because the acetylcholine receptors of mangoose render them resistant or immune to snake venom primarily composed of neurotoxin. Due to this the snake's venom fails to react the way it normally does to animals who are not immune to the venom.

So, the correct option is 'Mangoose'.

Which of the following statement is true?

  1. Hot air expands on heating.

  2. Hot air contracts on cooling.

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Air is a mixture which is composed of several gases like oxygen 21%, nitrogen 78%, carbon dioxide 0.03% and water vapors. The air molecules are held by strong intermolecular forces. When air is heated up, the air molecules absorb the heat and the intermolecular forces between the air molecules become weak and its kinetic energy increases. The air molecules move apart and become less dense and thus they expand on heating.
So, the correct answer is option A.
