Answer 1

because of this he has grown up to be quite strong

Answer 2

Swimming is a good sport it helps build muscle.

Step-by-step explanation:

This is the best example of a run-on sentence. A run-on sentence occurs when two independent clauses are joined in an improper way. These are complete sentences that can stand on their own. This is the case in this example as "swimming is a good sport" and "it helps build muscle" are both independent clauses.
