The composition of a cell differs from that of the cell membrane in that the cell membrane is
a. is mostly lipid while the whole cell is mostly aqueous.
b. mostly inorganic while the whole cell is mostly organic.
c. mostly protein while the whole cell is mostly nucleic acid.
d. is high in potassium while the whole cell is high in sodium.

The correct answer is A). Is mostly lipid while the whole cell is mostly aqueous .

This is because the cell membrane is majorly composed of the phospholipid bilayer. It is a protective covering present in all the cells.  

On the other hand, the whole cell other than the cell membrane is mostly aqueous. It contains 80% of water, therefore considered as aqueous. It is also referred to as cytoplasm of the cell. Most of the cellular activity including metabolic processes and signaling pathways occur within the cytoplasm of the cell.

ask your friends for what they got then copy it down if you don't have any friends which is fine than google it or pay the teacher
