HELP PLEASE The fluid mosaic model of membrane structure suggests that membranes

are composed of a single fluid layer of phospholipids and proteins
are composed of a fluid bilayer of fatty acids with proteins associated on the outer and inner surfaces
are composed of protein molecules embedded in a fluid bilayer of phospholipids
are composed of a fluid phospholipid bilayer sandwiched between two layers of hydrophilic proteins

eukarya because is is like alche and b is bacteria and d is animals

explanation:

b - the respond is innate and varies over time.

good luck!
