Question

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

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

(a) Both A and R are true and R is the correct explanation of A.

(b) Both A and R are true but R is not correct explanation of A

(c) A is true but R is false

(d) A and R are false

Answer 1

The correct option is: (b)

Explanation:

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 *****. 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.
