Explanation:

Mixture is a substance which has two or more components which do not combine chemically and do not have any fixed ratio in which they are present.

Homogeneous mixtures : It is a mixture that has uniform composition throughout the solution and the particle size or shapes are not different. There is no physical boundary between the dispersed phase and dispersion medium. Example: peanuts and almonds mixed together in a bowl,  a bucket full of sand and gravel

Heterogeneous mixtures : It is a mixture that has non-uniform composition throughout the solution and the particle size or shapes are also different. There is a physical boundary between the dispersed phase and dispersion medium.  Example:  food coloring dissolved in water, a cup of tea and sugar
