Detailed explanation-1: -The composition of Raisin Bran varies from scoop to scoop and is a mixture of raisin and flake “elements” that can be easily separated. Brass and bronze are made up of varying amounts of metals, depending on how it is made. The elements are not bonded in constant ratios, much like the raisins and flakes in Raisin Bran.
