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.
Both the extremities, flagella and cilia, are alike in that they help the cell in this mobilization. Thus, the answer to this item is letter "C. they assist with movement". With their appearances, both are hair - like structures but flagella are longer compared to the cilia.
Gene regulation is the control of when and where proteins are made.
Hope this helps :)
