B) 75,000 not fully sure tho
The checks and balances system in the Constitution is important because it helps to prevent any one branch of government from gaining too much power. The three main branches are the Executive, Legislative, and Judicial. Here are some examples. The President can veto a bill passed by Congress, preventing it from becoming law. This is an executive branch check on the legislative branch. In turn, the Congress can vote to override that veto with a two thirds majority in both the Senate and House, and the bill will become law. This is a Legislative check on the Executive branch. Finally, the Supreme Court, when ruling on a case, decide to use its power of judicial review to declare some law of Congress or act of the President unconstitutional. This is a judicial check on both the executive and legislative branches. Hope this helps
Answer:
Fort Sumter in Charleston, South Carolina was one of the four forts that had not yet been captured by the Confederates, so Lincoln wanted to keep the fort at all costs in order to keep the Union's strenght in the South. He sent unarmed ships to supply the fort with military and food supplies. The Confederate President Jefferson Davis gave command to Southern forces led by General Beauregard to bomb the fort on April 12 to force it to surrender, which happened.
The Northern states all supported Lincoln. He called for the fortresses to be reclaimed and the Union to be preserved. At the same time, 75,000 volunteers were called up for a period of 90 days. In the previous months, several governors had trained their militias. Their troops started to move the next day.
