The majority of the cell membrane is composed of what type of lipids?

The majority of the cell membrane is composed of PHOSPHOLIPIDS.

Explanation:

Phospholipids are a type of lipid that is found in the cell membrane of cells. This type of lipid are a good fit for cell membrane because they have the capacity to form bi layers. The lipids are divided into tail and head regions; the head is hydrophilic in nature while the tail is hydrophobic in nature.  The hyrophilic head is made up of phosphate group while the hydrophobic tail is made up of fatty acid molecules.

sulfur dioxide

explanation: acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. these substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
