Answer

Milk is a colloidal suspension in which tiny fat droplets are suspended in water.

Given enough time, they will settle out, which is why commercially sold milk is “homogenized” which just means it’s shaken very hard to break the fat into smaller droplets with will remain suspended longer.

Hence, Milk is a complex mixture of water, fat, protein, calcium, vitamins and other trace elements.
