Question

Skin of fingers shrink after washing clothes for a long time

Answer 1

hey mate :)

scientific reason -it is due to a phenomenon called osmosis

osmosis - it is the movement of solvent particles (I. e. water) from lower concentration of solute of higher concentration through a semi permeable membrane (I. e membrane of our epithelium tissues)

so when we remain in water for a long time the water from our fingers goes to outside and our fingers shrink... it is also called exosmosis

evolutionary reason - a long time ago shrinking in our fingers helps us to increase our grip strength in water like for capturing the prey and increasing our holding strength.. but this shrink thing is decreasing generation to generation but related to evolution..
