heya dear....(•‿•)

Explanation:

1 (☞ as the light is dim...cones will work there...but as they cant detect the colors properly...we are unabke to detect the colors...

2 (☞ if this layer is often removed the dust particles and other may enter into the ear ..and then they result in infection of ear..
