Question

There are 4 molecules moving across the membrane in this diagram. How many of

them are moving passively?

A) 1
B) 2
C) 3
D) 4

Answer 1

I think it should be C

Answer 2

C) 3

Step-by-step explanation:

So the one that has a group of three would be the Passive Transport the first one's effect would be Diffusion and the second and third are both together which will be Facilitated diffusion Hope this helps!

The rate of passive transport depends on the permeability of the cell membrane, which, in turn, depends on the organization and characteristics of the membrane lipids and proteins. The four main kinds of passive transport are simple diffusion, facilitated diffusion, filtration, and/or osmosis.
