can even get into his bedroom! John is

upset because he is certain this little brother

stole it and sprayed the cologne

everywhere, wasting the whole botse

When he goes into his bedroom he sees

the bottle is still on his nightstand He forgot

to put the lid on this morning. What type of

transport does this represent?

SIMPLE DIFFUSION transport

Explanation:

According to this question, John could smell the fragrance of his newly bought bottle of cologne all the way up the hall before he can even get into his bedroom, where he usually keeps it. However, he realizes when he got to his bedroom that he left the bottle of cologne uncovered.

The fragrance of the cologne that spreads from the bedroom all through the hall is as a result of SIMPLE DIFFUSION, a form of PASSIVE TRANSPORT. Diffusion is a form of passive transport in which molecules/fluids move from a region of high concentration to a region of low concentration until it is evenly spread. This is the case with John's cologne, which spread from the bedroom where the concentration is high to the hall, where it is low.
