The answer is:
In membranes phospholipids associate to form two layers.
Larger proteins float within the bilayer.
Integral membrane proteins can move laterally in a membrane.
Step-by-step explanation:
The fluid mosaic model is a model in which the structures of cell membranes are established. The flexible layer is made up of lipids, which are interspersed with a large protein. Other molecules can enter or leave through these channels.
