Answer:
The federal government is divided into three branches, the legislative, represented by the U.S. Congress, the executive, represented by the U.S. President and its cabinet, and the judiciary, represented by the Supreme Court, the Federal Courts, and the lower courts.
Explanation:
In the process of creating laws, it is Congress the organism that actually discuses, and passes the laws, although these laws can be proposed by the president and the cabinet in first place.
The president can veto the laws that Congress passes, but only once, and the president is in charge of executing and fulfilling the law.
Finally, the judiciary is in charge of revising and interpreting the laws. For example, the Supreme Court can strike down any law that it considers to be unconstitutional.
The most important of the three branches is the Congress, because without it, now laws would be created in first place.
