The specialized functions of different membranes are largely determined by the blank they contain. membrane lipids are blank molecules, composed of a hydrophilic portion and a hydrophobic portion. all cell membranes have the same blank structure, with the blank of the phospholipids facing into the interior of the membrane and the blank on the outside. the most common lipids in most cell membranes are the blank . the head group of a glycolipid is composed of blank .

Generally cell membrane is composed of lipid layer(phospholipid bilayer)which has hydrophobic head(phosphate group) which is water loving found outward of cell membrane And hydrophilic tail(hydrocarbon tail) which is water hating and it's found inward

answer; ///i believe the correct answer is (

homeostasis is the tendency towards a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes. and this is how it applies to the integumentary system. back to top. skin functions in homeostasis include protection, regulation of body temperature, sensory reception, water balance, synthesis of vitamins and hormones, and absorption of materials. when body temperature falls, the sweat glands constrict and sweat production decreases.
