The death of this leader resulted in a political and religious split within Islam. Who was he?

Muhammad was the founder/leader and when he died, there were a lot of issues about who would the new leader. The group split into the Sunni who wanted to elect their new leader and the Shia who thought it should be someone in Muhammad's family.

answer; ///first they would cross the atlantic ocean, and end up either in europe or africa; good luck

well, paralell is parallel. i am providing links to .

hope this !

a series circuit is one with all the loads in a row. there is only one path for the electricity to flow. if this circuit was a string of light bulbs, and one blew out, the remaining bulbs would turn off.

unlike in series circuits, a charge in a parallel circuit encounters a single voltage drop during its path through the external circuit. the current through a given branch can be predicted using the ohm's law equation and the voltage drop across the resistor and the resistance of the resistor.

a parallel circuit has certain characteristics and basic rules: a parallel circuit has two or more paths for current to flow through. voltage is the same across each component of the parallel circuit.
