what is the meaning of the term diffusion?
transport across a membrane requiring a transport protein but not requiring energy
transport or dispersing of molecules until there is a uniform concentration of molecules throughout a solution
transport of materials or molecules small enough to cross through pores in a membrane
transport of water to dilute molecules that are highly concentrated on the other side of a membrane

Explanation:

• For the first question, facilitated diffusion is the process where a molecule moves into the cell through a transport protein without energy. Active transport requires energy, filtration is different from the described process, and osmosis is specifically about water movement.
• For the second question, diffusion is the transport or dispersing of molecules until there is a uniform concentration of molecules throughout a solution. The other options describe different transport - related concepts.

Answer:

1. A. facilitated diffusion
2. B. transport or dispersing of molecules until there is a uniform concentration of molecules throughout a solution
