Question

the fluid mosaic model of the cell membrane explains its permeability. the tails of the phospholipid bilayer prevent molecules from passing through without the assistance of a. non selective transport protein hydrophilic vesicle polar hydrophobic complete

Explanation:

The cell - membrane has selective permeability as described by the fluid - mosaic model. The hydrophobic tails of the phospholipid bilayer prevent polar and hydrophilic molecules from passing through without a transport protein.

Answer:

selective, hydrophobic, polar and hydrophilic, transport protein
