Discussion
Read statements (A) and (R) properly and then answer the following questions.
(A) : Silkworm can find his female worm from many kilometers away by her smell.
(R) : Some female insects release 'Pheromones' which can be recognised by their males by smell.
Choose the correct answer :
Answer: A
Both (A) and (R) are correct and (R) explains (A).
The male silk moth can find a female from a long distance, even kilometres away, by her smell, as NCERT's EVS chapter on animals' senses describes. The reason gives the explanation: female insects such as the silk moth release chemicals called pheromones, which males detect with their antennae and follow to the female.
Since the pheromone is the 'smell' the male follows, (R) directly explains (A), which rules out the other options.
