Step-by-step explanation:
Checks and Balances in a democratic American government refers to a system where each branch (executive, judicial, and legislative) has the power to limit or influence the other branches. This system is designed to prevent any one branch from becoming too powerful. For example, if the president vetoes a bill passed by Congress, Congress can override the veto with a two-thirds majority vote. Similarly, the Supreme Court can declare a law passed by Congress as unconstitutional through judicial review.
