1) Hundreds of people are waiting outside an empty movie theatre waiting to run in and claim seats to see Puss in Boots. All entrance to the theatre is through a single turnstile, monitored by an usher checking tickets. When the theatre doors open and people first start moving into the theatre, which transport process does this most resemble (simple diffusion, facilitated diffusion, or active transport) AND WHY?


2) An hour later, the same theatre is completely filled with a movie-goer in every seat plus another 100 people standing in the aisles and crowding the entrance to the theatre. One last person is outside the turnstile, desperately wanting to get in the theatre. If the usher pushes all the people crowding the door out of the way and shoves the last person inside the door to the theatre, what transport process does this most resemble AND WHY?

It was deleted as it is quite obviously homework and possibly as it didn't get a reply - makes finding plagiarized answers a bit harder. There was another part too.
