Final answer:
Cultures influence each other through interaction and exchange, leading to the assimilation and adaptation of various cultural elements. An example is the American adaptation of sushi, which has resulted in new food traditions.
Step-by-step explanation:
Cultures influence one another through various processes such as globalization, trade, immigration, and the exchange of ideas and technologies. When people from different backgrounds come together, they often share and assimilate aspects of their culture such as language, food, music, and dress. This exchange can lead to changes in societal norms, fashion, cuisine, and more.
An example from American life today that illustrates cultural influence is the popularity of sushi. Originally a Japanese cuisine, sushi has been Americanized with adjustments to suit the local palate, such as the introduction of the California roll. This not only shows the integration of Japanese culinary culture into American life but also how cultures adapt and create new, blended traditions.
