<span>d. neither of these will cross a plasma membrane.
Glucose cannot diffuse across a plasma membrane as it is polar. Since the question doesn't specify the type of diffusion, simple diffusion is assumed.
If you count facilitated diffusion, then A is the answer.</span>
Stored energy. Also this should have been listed under physics lol
Character displacement refers to the phenomenon where differences among similar species whose distributions overlap geographically are accentuated in regions where the species co-occur, but are minimized or lost where the species' distributions do not overlap.
