Respuesta :
The phospholipid bilayer is a thin polar membrane made of two layers of lipid molecules. ... Biological bilayers are usually composed of amphiphilicphospholipids that have a hydrophilic phosphate head and a hydrophobic tail consisting of two fatty acid chains.
Answer:
Phospholipids
Explanation:
Phospholipids make the bilayer of the cell membrane. Phospholipids are polar components that have a head which is hydrophilic and a tale that is hydrophobic. When they make the bilayer of the membrane cell the heads of the phospholipids are orientated to the exterior and the inside of the cell while the tales are touching each other and not having any contact with the exterior or interior of the cell.
