Answers (1)
Assertion (A) states that cockroaches can perceive multiple images of an object through the use of several ommatidia, known as mosaic vision. This is a correct statement as cockroaches have compound eyes consisting of numerous ommatidia, each capable of capturing a separate image of an object.
Reason (R) states that mosaic vision provides increased sensitivity but lower resolution. This is also a correct statement. Mosaic vision allows cockroaches to have a wide field of view and enhanced sensitivity to detect motion and potential threats in their surroundings. However, each individual ommatidium has limited resolution, resulting in a less detailed image compared to other forms of vision.
While both Assertion (A) and Reason (R) are correct, Reason (R) does not provide a direct explanation for Assertion (A). The fact that mosaic vision provides increased sensitivity but the lower resolution is related to the functioning of ommatidia, but it does not specifically explain why cockroaches can perceive multiple images. Therefore, Option 4 is the correct answer as it states that both Assertion (A) and Reason (R) are correct, but Reason (R) is not the correct explanation of Assertion (A).
