Answer:
a. It's a carrier protein doing facillitated diffusion
Explanation:
Facilitated diffusion may be defined as the transportation of molecules from a high concentration to a low concentration that is down the concentration gradient without input of the energy. Whereas the active transport is transportation of the molecules from the low concentration to the high concentration which is against concentration gradient by the membrane protein.
The glucose transportation process requires membrane protein for the transport and does not require any energy. Therefore, it is carrier protein which is doing the facilitated diffusion.

Compositional layers are determined by their components, while mechanical layers are determined by their physical properties.
The secondary consumers will be able to survive, as well as decomposers, as they kill the primary consumers, which depends on the plants, and teaches them to their offspring
