What area of egypt is known as "upper egypt"

Well..it's described as a narrow, fertile area which is about 3km wide and includes four fifth of the length of the Nile!! hope it helps :)

They made a checks and balance system to equal power within the branches. the "check" meant that one branch would watch one branch and "balance" them if they were too powerful. if you want more info on this, i would just google checks and balance system.

Ibelieve it belongs to the president.
