1. Immigration <em>has triggered</em> the development of different and new cultures around the world.
2. The customs and the different languages <em>are mixed</em> with the ones already established in a determined place.
Each sentence contains a subject and a <em>verb.</em> The two sentences are joined with a comma and a <u>coordinating conjunction</u>, in this case <u>for</u>, which is used to express reasons.
