Question and answer
What is a real life example of selective permeability?
or-Tex fabric: an artificial fabric that is engineered to let water vapor pass through, but won't pass liquid water. [ An eggshell: the egg shell is a natural structure that allows oxygen to pass through, but keeps the liquid contents of the egg inside. Reverse osmosis water filter: the RO water filter contains a man-made polymeric material that selectively allows water molecules to pass
through, but keeps minerals from passing. Kitchen colander: allows you to separate the spaghetti from the water by virtue of holes that are sized to keep large solids inside. Chain-link fence: the fence has a mesh that allows air, insects, and light to pass through, but keeps people and animals from getting through. ]
