Legislative Preview & How a bill becomes a law

Some areas that I didn't know are that there are 35 people in the senate and 70 in the House. I didn't know that the bill could be taken back to House or the senate and it can be looked at again and it can over power the governors decision to veto the bill and make the bill pass. Also, i didn't know once a bill is assigned to a committee, the chair decides when the bill will be heard. Some areas that I do have prior knowledge on is I do know that the bill gets drafted and goes to  the House of Representatives.
