Answer:
Bicameralism
Step-by-step explanation:
The United States adopted a bicameral legislature which means that the legislative branch has two separate houses. One, that represented the people, the House of Representatives and the Senate, that represents the States. The bicameral system was created because the founding fathers believed that power should be shared with all units of government. It came after a big discussion between small states, that demanded equal representation than bigger states. The Great Compromise created two houses.
