How does the fluid mosaic model represents the structure of the plasma membrane? Select the correct response(s) The proteins are embedded which are exclusively passing through the lipid bilayer. The proteins are embedded which can be located at one side of the lipid bilayer or passing through it. The primary component is the phospholipid bilayer with the hydrophilic phosphate head at the core. The primary component is the phospholipid bilayer with the hydrophobic phosphate head at the core. The primary component is the phospholipid bilayer with the hydrophilic hydrocarbon tail at the core. The primary component is the phospholipid bilayer with the hydrophobic hydrocarbon tail at the core. The proteins are embedded which are exclusively located at one side of the lipid bilayer.
