Answer:
Reverse Osmosis.
Explanation:
This is the mechanisms of water purification for drinking water which is droven by the chenical potential of the solvent .
It involves the use of partiaiy permeable membrane to allow ions , water molecules ,solvent molecules to pass through during purification
A pertial permiable menenrane in this prurifiction process is the membrane that allow only water molecules, ions and restricted other unwanted chemical contaminants from passing through it.
A. Would be the correct answer!
Well let's take Sedimentary rock for example, The Law of Superposition which measures the average age of Sedimentary rocks using rocks around it. So you would use that rocks below it are older and that Extrusions and Intrusions are younger than the rocks which are stable.
