Question

Carol, Upper Norwood

Answer

** Definitive **
Name: James O'Brien
Qualification: Nothing I don't know about osmosis
Answer: The answer is……. OSMOSIS! The water passes through a semi-permeable membrane in the skin, meaning there is more fluid in your fingers. As the skin is connected to the tissue, the fingers wrinkle to create a greater surface area.
