1. Beneath the epidermis, a layer called '' Stratum germinativum'' continuesly make epithelial cells... Hence they never disappear.
2. For some of us, when they are told to speak infront of large audience... We feel stressed & our Adrenal gland releases stress hormone(Adrenaline) which forms a platform for us to either fight or flight away...it increases heart beat,alertness,metabolism & dilation of blood vessels which gives red appearance to our face.
3. Because, to see in low Light our eye have to undergo some reactions in Rod cells of Retina which takes a little time.
