Question

each of the following is an example of passive transport except

Answer 1

What are the answer choices?

Answer 2

Passive transport is a kind of transport where molecules move along a concentration gradient from an area of higher concentration to an area of lower concentration, keywords being higher to lower. There are different kinds of passive transport, but the major types include: simple diffusion, facilitated diffusion, filtration, and osmosis.

Answer 3

So your answer would not be any of the types of transport listed above (they are all passive transport), and would probably be a form of active transport (movement from lower concentration to higher concentration).
