3.) Can you explain how signals are received by sensory receptor cells in the ear and then
transmitted to sensory neurons? // Can you identify functions of the different parts of the
ear? How are mechanical waves converted into signals within the ear? -----

4.) Can you identify functions of the different parts of the ear? How are mechanical waves
converted into signals within the ear? // Can you identify cells that make up the retina
based on their function?
