Answer:
This is actually pretty easy. You can use anything that contains two or more items to make a mixture. For example, sand, water, and gravel is mixed to make cement, great for fixing roads. Two more you can use are Chlorine, caustic soda, and water (bleach) for whitening clothes in the washer and Plasma, white blood cells, red blood cells, and platelets (blood) which keeps your body up and running. I'm not so sure about explaining if its heterogeneous or homogeneous. But I hope this helps!
