active transport
filtration
osmosis
question 16

what is the meaning of the term diffusion?
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
transport across a membrane requiring a transport protein but not requiring energy
transport or dispensing of molecules until there is a uniform concentration of molecules throughout a solution

Explanation:

1. For the first question, facilitated diffusion is the process where molecules move into the cell through a transport - protein without the need for energy. Active transport requires energy, filtration is based on pressure - gradient, and osmosis is specifically for water movement across a semi - permeable membrane.
2. For the second question, diffusion is the transport or dispersing of molecules until there is a uniform concentration of molecules throughout a solution. The first option describes simple diffusion through pores, the second is related to osmosis for water movement to dilute concentrated molecules, and the third is facilitated diffusion.

Answer:

Question 15: A. facilitated diffusion
Question 16: D. transport or dispersing of molecules until there is a uniform concentration of molecules throughout a solution
