Both balance and hearing use hair cells, but balance senses light waves and hearing senses sound waves.

Answer 1

Both balance and hearing use the ear, but balance senses movement of the body and hearing senses sounds.

Explanation: Both functions rely on hair cells in the inner ear—vestibular organs detect head/body movement (balance) and the cochlea detects sound waves (hearing).
