Final answer:
The principle of the Constitution likely in question is the separation of powers, aimed at distributing governmental power to prevent its concentration and protect citizens' rights. The purpose is to ensure a balanced system with checks and balances, and the Constitution can be both formally and informally amended.
Step-by-step explanation:
The principle of the Constitution represented by this chart is most likely the separation of powers, which includes the distribution and balance of governmental powers across different branches to protect the rights and liberties of the people. This principle, outlined by figures like Thomas Jefferson, specifically divides the government into the Legislative, Executive, and Judicial branches as laid out in Articles I, II, and III of the Constitution. The purpose of this separation is to prevent the concentration of power and to ensure a system of checks and balances, where each branch can limit the power of the others. Additionally, the Constitution can be amended both formally, through the process described in Article V, and informally, through judicial interpretation and practice, which keeps the Constitution as a living document adaptable to changing times.
