is juice squeezer selectively permeable? Why?

Answer 1

No, a juice squeezer is not selectively permeable. Selective permeability refers to a membrane or material that allows only certain substances to pass through while blocking others. In the case of a juice squeezer, it is a mechanical device that physically extracts juice from fruits or vegetables by applying pressure. It does not have a selectively permeable membrane as it is not involved in deciding which substances can go through.
