Answer:
a. derivatives of triacylglycerols that contain a polar phosphate head and an amino alcohol at one of the positions of the glycerol group.
Explanation:
Glycerophospholipids consist of glycerophosphate which is an ester of glycerol and phosphoric acid, long-chain fatty acids, and certain alcohols. The glycerophospholipids is responsible for the formation of cellular membranes of organelles within cells of all organisms. The name of Glycerophospholipids indicates the presence of glycerol, phosphorus and lipids so that's why we can say that it is derivatives of triacylglycerol that contain phosphate and an amino alcohol at one of the positions of the glycerol group.
The ozonosphere is another term for the ozone layer, which is within the Earth's stratosphere. The ozone layer is responsible for absorbing most of the sun's ultraviolet (UV) radiation, thanks to its high concentration of ozone that is exclusive to this layer.
The plasma membrane or the cell
membrane is the one that protects the cytoplasm of a cell. It is mostly
composed of lipids and proteins. It has a phospholipid bilayer that controls
the entering and exiting of molecules in the cell and at the same time,
provides protection for the cell or plasma membrane. It has polar head and a
nonpolar tail. Proteins embedded within the phospholipid bilayer have the same
function of the plasma membrane that includes selective transport. The
phospholipid bilayer consists mainly of the lipid molecules.
