Question

Is blood homogeneous or heterogeneous. What exactly it is ?

I want brief explanation about it.

Answer 1

1. "Blood is a heterogeneous mixture because the blood cells are physically separate from the blood plasma.
2. A heterogeneous mixture is made of different substances that remain physically separate. Heterogeneous mixtures always have more than one phase (regions with uniform composition and properties).
3. The cells of blood have different properties than the plasma. The cells can be separated from the plasma by centrifuging, which is a physical change."
