Final answer:
Federalism is a system of government dividing power between national and state governments, affecting laws and regulations.
Explanation:
Federalism is a system of government where power is distributed between a national/federal government and various independent state governments. This division of powers and responsibilities among national, state, and local governments is a core aspect of federalism.
For example, in U.S. federalism, states can regulate trade within their borders, while only the federal government can regulate commerce that crosses state lines.
Intergovernmental relations play a significant role in federalism, as both levels of government have certain powers and areas where they can create laws and regulations independently.
