Is bowl of raisin bran cereal heterogeneous or homogeneous?

A heterogeneous mixture is a mixture in which the components are not evenly distributed throughout the mixture. In other words, the different components of the mixture can be seen and distinguished from each other. In the case of raisin bran cereal, the raisins and the bran flakes are two distinct components that can be seen and distinguished from each other.
