Answer:
Colloid :A mixture in which microscopically insoluble particles are suspended throughout another substance
Emulsion: A mixture in which two or more liquids are mixed that normally are not mixable
Heterogeneous : Mixture that has its different components mixed unevenly within the substance
Homogeneous : Mixture that has its different components mixed evenly within the substance
Step-by-step explanation:
Colloids are solutions in which small sized particles are suspended throughout the solution as they do not settle own their own. Example: Blood
Emulsion : is a mixture of two liquids that normally do not mix. Example: Oil in water
Heterogeneous mixtures : It is a mixture that has non-uniform composition throughout the solution and the particle size or shapes are also different. Example: sand in water
Homogeneous mixtures : It is a mixture that has uniform composition throughout the solution and the particle size or shapes are not different. Example: Sugar in water
