Answer:
The homogeneous mixture is only in the one phase of matter, whereas heterogeneous mixture is always in two or more than two different phases of matter. Solutions are termed as the homogeneous mixtures, on the other hand, suspensions or colloids are termed as the heterogeneous mixtures.
Examples:
Homogeneous:
Bronze: this alloy is an example of homogeneous substances since it is composed of tin and copper.
Milk : this mixture that we see in a uniform way is composed of substances such as water and fats.
Heterogeneous:
Mixtures in two or more phases are heterogeneous mixtures. Examples include ice cubes in a drink, sand and water, and salt and oil. The liquid that is immiscible form heterogeneous mixtures. A good example is a mixture of oil and water.
The horrific forced transport of Africans into America during the age of exploration as part of the slave trade that was going on where Africans were transported on ships from Africa, chained up like animals all the way to America was an example of international migration affecting the population.
External influences forced Africans to go from Africa to another continent and live there.
