Answer:
Separation of Powers
Step-by-step explanation:
The U.S. government is based on the principle of Separation of Powers; this principle refers to the division of power and responsibilities of the government into three branches: The judicial, the Executive and the Legislative, and it prevents the government from being controlled by one branch, and it also sets the basis for the checks and balances system in which all branches oversee, check and limit the power of each other.
