15 points please help Models of the human immunodeficiency virus (HIV) and an animal cell are shown below.

What is the difference in the function of the glycoprotein structures of an HIV virion and the cilia
of an animal cell?
The glycoprotein structures are used for attachment, and the cilia are used to move fluids
surrounding the cell.
The glycoprotein structures are used to obtain nutrition, and the cilia are used to secrete
proteins.
The glycoprotein structures are used to provide physical support for the viral envelope, and
the cilia strengthen the cell membrane.
The glycoprotein structures are used for defense, and the cilia are used for locomotion.
