Question

which statement describes the path of information in the fish when it responds to movement in the water?
a. the eyes send signals to the sensory hairs, which then send signals to the muscles.
b. the sensory hairs send signals to the brain, which then sends signals to the muscles.
c. the eyes send signals to the brain, which then sends signals to the sensory hairs, which then send signals to the muscles.
d. the sensory hairs send signals to the eyes, which then send signals to the brain, which then sends signals to the muscles.

Explanation:

Fish detect water movement using sensory hairs (in their lateral line system). These sensory hairs send signals to the brain for processing, and the brain then sends signals to the muscles to produce a response. Other options incorrectly sequence the sensory input, processing, and motor output pathway.

Answer:

B. The sensory hairs send signals to the brain, which then sends signals to the muscles.
