In an essay of 400 words, summarize the responsibilities of the three branches of the united states government and the system of checks and balances. what is the purpose of the system of checks and balances?

There is a system in the united states constitution, which was made practically to control the amount of power each branch of government has. this system is called checks and balances and it is very important to our government. without a system to prevent one branch of government from having more power over another, the government would be controlled by one group of people. it would not be fair to the people of the united states if one branch had more power over another. this system is intended to prevent tyranny.
