Question

Assertion: Snakes exposed to gamma rays become non-poisonous.

Reason: Poisonous snakes have poison glands and a pair of fangs. They are affected by gamma rays.

• A. Both are true with reason being correct explanation of assertion.
• B. Both are true but reason is not correct explanation of assertion.
• C. Assertion is true but reason is wrong.
• D. Both reason and assertion are wrong.

Answer 1

The correct option is A Both are true with reason being correct explanation of assertion.

Snakes exposed to gamma rays become non-poisonous as gamma rays bring conformational changes in the poison leading to loss of its toxicity.

Gamma rays are high energy radiations that can pass through all the living cells leading to their death.

So, on exposure to gamma rays poison glands would be affected but the snakes would become non-poisonous due to loss of toxicity of their venoms.

So, the correct answer is 'B'.
