Question

When we are swimming, which layer of the skin keeps us waterproof?
  1. Epidermis
  2. Dermis
  3. Hypodermis
  4. Melanin


Solution

The correct option is A Epidermis
Epidermis is the outermost covering of our skin, followed by the inner layers dermis and hypodermis. Epidermis provides a waterproof barrier and contains a substance called melanin which gives our skin its colour. It also provides a barrier against infection from the outside environment.
