"Bicameral" refers to a legislative system that consists of two separate chambers or houses. This structure is designed to provide a system of checks and balances within the government. Each chamber typically has distinct powers and responsibilities, allowing for more thorough debate and consideration of laws. Many countries, including the United States, have a bicameral legislature. In the U.S., this system is represented by the Senate and the House of Representatives. Each chamber must approve a bill for it to become law, ensuring that multiple perspectives are considered in the legislative process.
