When using a medicine dropper, you squeeze the rubber bulb and insert the end of the tube into a liquid. Why does the liquid rise inside the dropped when you release the bulb?

when you squeeze the medicine dropper, it forces the air out of it and creates a vacuum inside the dropper. When you put it into the liquid, and release it, the atmospheric AIR pressure (14 lbs/square inch) forces the liquid INTO the medicine dropper, which is in a state of vacuum, or LOWER air pressure AS you release it.

because thee ball creates suction to make the fluid rise. and when it stops sucking , the suction trapped in the top, holds the liquid up. if you tip it sideways, the fluid will run out.

Quite simple.
Indeed, it 'sucks'.
Get an "A".
