There are a few vital characteristics to mention here. First we have to know about which ions we're talking about as the cellular membrane is semi-permeable (lets some flow freely through the membrane and some not), it depends on the size of the compounds, and also the charge that a molecule has.
Since a hypothesis is a statement rather than a question, you could simply restate the line given to you in line 1. (That is of course your hypothesis is on the subject of people and social media.)
If I were to make a hypothesis off of that subject I would use something along the lines of:
