Answer: If freeze fracture technique used in the fluid mosaic model we can found membrane proteins are randomly dispersed throughout the phospholipid bilayer and integral transmembrane protein that span entire membrane
Explanation:
Freeze fracture is a technique which can be used for visualized membrane structure and protein distribution.in this technique first a cell is rapidly frozen in liquid nitrogen.after that it cleaved lipid bilayer .then two section are coated with platinum, then acid is used to dissolve organic material resulting a replica in the surface will be obtained. then replica are view in electron microscope.
we can found protein are embedded in the lipid bilayer.
