When a mouse cell and a human cell are fused, the membrane proteins of the two cells become uniformly distributed over the surface of the hybrid cell. This occurs because
A) all proteins in the plasma membrane come from a membrane other than the human or the mouse.
B) all proteins are anchored within the membrane.
C) proteins are asymmetrically distributed within the membrane.
D) many proteins can move around within the bilayer.
E) different membranes contain different proteins.

This occurs due to the fluid nature of the plasma membrane, allowing many proteins to move laterally within the lipid bilayer, leading to the mixing and redistribution of mouse and human cell membrane proteins over the surface of the hybrid cell.
