Final answer:
Blood is a heterogeneous mixture that qualifies as both a suspension and a colloid. It is not homogenous or a solution due to its composition and the size of its particles.
Step-by-step explanation:
Blood can be described using several terms: heterogeneous, suspension, and colloid. It is a heterogeneous mixture because its composition is not uniform throughout, and different components like plasma, red blood cells, white blood cells, and platelets can be identified. As a suspension, blood contains particles that are large enough to eventually settle out if left stationary. Meanwhile, some components of blood also behave like colloids where particles are dispersed throughout but do not settle out quickly, such as proteins in plasma. Blood is not a homogenous mixture, as it does not have the same composition throughout, nor is it a solution, because its components are not dissolved to the molecular or ionic level but rather suspended.
