Question

The lateral line system of lower vertebrates (like fish) performs what function in common with the inner ear, at the level of the basilar membrane and hair cells?

Select one:

a. Converts vibrations in the air to vibrations in fluid

b. Converts mechanical signals, specifically vibrations in fluid, to electrical signals

c. Sends feedback to hair cells

d. Sends out sounds for echolocation

Answer 1

Ans. Option B is the correct answer.

EXPLANATIONS:- In dishes the lateral line system is present. It is used for the detection of the movement, vibration and pressure gredient in the surrounding water. The sensory ability is achieved by the modified epithelial cells called as the hair cells. The hair cells convert mechanical signals specifically vibration in fluids to electrical signals.
