Answer 1

Answer:

Claim 2: Earthworms can respond to light.

Explanation:

Yes, earthworms do not have eyes. However, sensory organs of animals isn't restricted to the eyes alone. Other sensory organs include, ears for hearing, nose for smelling and so on. In terms of response to light, the eyes as a sense organ comes into play. However, the skin is also a sense organ which has the ability to feel the effect of a phenomenon such as as heat or respond to touch. Because light produces heat, earthworms can respond to light through their skin. With their skin they can measure the intensity of light falling in them and adjust depending on their current body temperature.

Therefore, earthworms can respond to light with their skin.
