Question

In science class, your teacher opens a perfume bottle to model cell transport. She asks the students to identify the type of cell transport and to explain the method of movement. Which of the following is the best explanation for this model? *
A.) This model demonstrates osmosis, because the perfume molecules are moving from an area of high concentration to low concentration.
B.) This model demonstrates osmosis, because the perfume molecules are moving from an area of low concentration to high concentration.
C.) This model demonstrates diffusion, because the perfume molecules are moving from an area of high concentration to low concentration.
D.) This model demonstrates diffusion, because the perfume molecules are moving from an area of low concentration to high concentration.

Answer 1

The answer is C cuz the perfume is moving from a high concentration to a low concentration

Answer 2

C. The perfume molecules are diffusing around the room. As these molecules drift from each other they begin to diffuse around other gases like oxygen. This is why when you spray a perfume right in front of you it’s too concentrated (or too much) to breathe in but once the perfume is able to diffuse and spread out it is able to be smelled without hurting your nose!
