Final answer:
Sub-communities, or subcultures, are groups that arise within larger communities based on shared attributes or interests, such as the body modification community, ethnic and racial group subcultures, biker culture, and the LGBTIQ+ and bohemian communities, which contribute to the creation of vibrant neighborhoods.
Step-by-step explanation:
Sub-communities, or subcultures, are groups that form within larger communities, often based on shared interests, heritage, or lifestyle. For example, the body modification community arises from individuals who embrace physical alterations to their appearance through tattoos, piercings, and plastic surgery. Similarly, certain ethnic and racial groups form subcultures around common languages, food, and customs inherited from their countries of origin. Other subcultures may form around social and recreational activities, as with the biker culture, revolving around an avid interest in motorcycles. Moreover, the LGBTIQ+ community and bohemians often create vibrant and eclectic neighborhoods, celebrating diversity and creating enclaves with rich cultural amenities.
