The constitution reflects the principle "separation of powers" because it

makes the president distinct from the executive branches

organizes each state into a bicameral system of branches

distributes power between three branches of government

lists specific powers that belong to the state governments

distributes power between three branches of government

Explanation:

The Constitution separates power in three branches: the Legislative, the Executive, and the Judicial. Each of these branches has independent and separate powers, making it possible to have a healthy power distribution. The idea was stablished by Montesquieu in order to prevent the rule by iron fist.

In the United States the powers are:

- The Legislative, set up in Article 1. Composed of the House and Senate.

- The Executive, set up in Article 2. Composed of the President, Vice-President, and the Departments.

- The Judicial, set up in Article 3. Composed of the federal courts and the Supreme Court.
