Imagine that a scientist is able to reverse the principles of diffusion, such that molecules preferentially move from regions of low concentrations to regions of high concentrations. How would this affect the morphology of bacteria?
A)This change would not likely affect bacteria morphology, as diffusion plays no role in determining bacteria shapes.
B)Bacteria would have to actively transport molecules across the cell membrane, potentially allowing for bacteria to grow larger.
C)Bacteria would have to prevent the diffusion of molecules out of the cell, potentially allowing for bacteria to grow wider.
D)Bacteria would have to actively transport molecules across the cell membrane, potentially allowing for bacteria to grow larger, and would have to prevent the diffusion of molecules out of the cell, potentially allowing for bacteria to grow wider.

If molecules preferentially moved from regions of low concentrations to regions of high concentrations, bacteria would have to actively transport molecules across the cell membrane to maintain a high concentration inside the cell. This would potentially allow for bacteria to grow larger. Additionally, bacteria would have to prevent the diffusion of molecules out of the cell, potentially allowing for bacteria to grow wider. Thus, both options B and C are likely, resulting in answer choice D being the best choice.
