In which direction does the head of the molecules of the plasma membrane face? toward the outside toward the middle away from water toward the head of another molecule

The head of the molecules of the plasma membrane face towards the outside.

Option A

Explanation:

Phospholipids is arranged in a bi-layer, makes up the structure of the plasma layer. The hydrophilic segment of a plasma membrane is its head, and it has a high affinity towards the water. The hydrophilic heads of phospholipids in a layer bi layer faces outward, reaching the (watery) liquid both inside and outside the cell.

The hydrophobic, or "water-dreading" portion of a phospholipid comprises of its long, non polar unsaturated fat tails. The unsaturated fat tails can be without much of a stretch communicate with other non polar atoms, yet they cooperate inadequately with water.

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
