Question
Assertion (A) - Metamorphosis is not shown by humans.Reason (R) - In human baby, body parts similar to an adult are present since the time of birth.(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 the correct explanation of A.(c) A is true but R is false.(d) A is false but R is true
Solution
The correct answer is (b) Both A and R are true but R is not the correct explanation of A.
Explanation: Assertion (A) is true because humans do not undergo metamorphosis. Metamorphosis is a biological process by which an animal physically develops after birth or hatching, involving a conspicuous and relatively abrupt change in the animal's body structure through cell growth and differentiation. This is common in insects and amphibians, but not in humans.
Reason (R) is also true because human babies do have all the body parts similar to an adult since the time of birth. However, this is not the correct explanation for Assertion (A). The reason humans do not undergo metamorphosis is not because they are born with all body parts, but because their development is different, characterized by a continuous growth and maturation process, not a sudden change in body structure.
