What divides the earth into the eastern and western hemisphere * 1 point?

The Prime Meridian
The Prime Meridian divides the globe into Eastern and Western hemispheres, just as the equator divides the globe into Northern and Southern hemispheres. The Prime Meridian is at 0 degrees longitude, just as the equator is at 0 degrees latitude.

How many degrees are there per line of longitude and latitude?

Lines of latitude and longitude intersect, creating a grid that allows anyone in any location to pinpoint a geographic location. There are 360 degrees of longitude (because meridians make Great Circles around the globe), and there are 180 degrees of latitude.
