Identify each of the following mixtures as either homogeneous or heterogeneous and as a solution, a suspension, or a colloid. blood a. homogeneous b. heterogeneous c. solution d. colloid e. suspension salad dressing a. homogeneous b. heterogeneous c. solution d. colloid e. suspension

Blood.

Blood is heterogeneous because it has corpuscles (blood cells and platelets) physically suspended in blood plasma.   Blood plasma and the corpuscles have different properties and can be separated by methods such as centrifugation. Also, blood is considered a colloid suspension because it has the properties of both a colloid and a suspension. This is because the blood plasma acts as a colloid. More so, if blood was left to settle,then the blood cells would collect at the bottom hence taking the characteristic of a suspension.
