To determine the best explanation of the process illustrated in the diagram, we need to consider the provided options:
A. **Passage of water molecules through a semi-permeable membrane to equalize concentration** - This option describes osmosis, which involves the movement of water, but does not specify the transport of other types of molecules.
B. **Transport of molecules across a membrane from a high to low concentration by means of a carrier protein** - This option refers to facilitated diffusion, where molecules move down their concentration gradient with the help of a carrier protein.
C. **Movement of molecules against a concentration gradient expending energy** - This option describes active transport, which requires energy to move molecules from a low concentration to a high concentration.
D. **Separation of suspended particles from a fluid environment to a non-fluid environment through a porous membrane** - This option describes filtration or a similar process rather than a specific transport mechanism.
Based on the typical cellular processes addressed by these options, **B** (transport of molecules across a membrane from a high to low concentration by means of a carrier protein) is often illustrated in diagrams depicting facilitated diffusion.
If the diagram you are referring to shows the transport of molecules via a carrier protein without involving energy expenditure (i.e., it illustrates facilitation rather than active transport), then **B** is the best answer.
However, if the diagram instead indicates energy expenditure to move against a gradient, then **C** would be appropriate.
In conclusion, without the specific diagram but based on common processes described, the best explanation would likely be **B** if it represents facilitated diffusion. If it indicates active transport due to energy use, then choose **C**. Please select based on the diagram's specifics.
