Fact 1: Vesicle transport requires energy, so it is also a form of active transport.

Given the two facts above, answer the question "what is a form of diffusion?" with the following options: 
- Move to another area
 - vesicle transport
 - By wind and rain
 - through water
 - Soil movement
 - by making heat
 - Evaporation
