Through which process does the skin slow down the evaporation of water?

Absorption
Insulation
Respiration
Transepidermal Water Loss (TEWL)

The correct answer is: Absorption

The correct answer is absorption. Absorption is the process through which the skin slows down the evaporation of water by taking in moisture and hydrating the skin. This process helps maintain the skin's natural barrier and prevent dehydration. Insulation does not directly slow down the evaporation of water but rather helps regulate body temperature. Respiration is the process of breathing and is not related to the skin's ability to retain moisture. Transepidermal Water Loss (TEWL) refers to the loss of water through the skin rather than slowing down evaporation.
