Answer:
A society will be considered to has a dynamic and heterogeneous culture if it <em><u>possessed wide variety of cultural identity</u></em> (such as different ethnicity, traditions, language, etc.) and their culture are constantly evolving as they interact with one another.
Micro-culture is the type of culture that is not common in a society, because it only held by small percentage of people in that society.
Societies who maintain communication with micro-culture will give a chance for people in that culture to fully express their heritage and assimilate their cultures with the mainstream culture, resulting in a new combination between the two.
This will add the notion that the society has a dynamic and heterogeneous culture.
