based of the fluid mosaic model of cell membranes, which of the following statements about membrane phospholipids is
true?
o they can move laterally along the plane of the membrane.
o they frequently flip - flop from one side to the membrane to the other.
o they occur in an uninterrupted bilayer, with membrane proteins restricted to the surface of the membrane.
o they frequently leave the bilayer and dissolve in the surrounding solution.

Explanation:

According to the fluid mosaic model, phospholipids in the cell membrane can move laterally along the plane of the membrane. Flip - flop movement (from one side of the membrane to the other) is rare. Membrane proteins are not restricted to the surface but can be embedded in the bilayer. Phospholipids do not frequently leave the bilayer and dissolve in the surrounding solution as they are part of the stable membrane structure.

Answer:

they can move laterally along the plane of the membrane.
