Question

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?
A. The glycoprotein structures are used for attachment, and the cilia are used to move fluids
surrounding the cell.
B. The glycoprotein structures are used to obtain nutrition, and the cilia are used to secrete
proteins.
C. The glycoprotein structures are used to provide physical support for the viral envelope, and
the cilia strengthen the cell membrane.
D. The glycoprotein structures are used for defense, and the cilia are used for locomotion.

Answer 1

The glycoprotein structures of an HIV virion are used for attachment, while the cilia of an animal cell are used to move fluids surrounding the cell.Option A is the correct answer.

Step-by-step explanation:

The difference in the function of the glycoprotein structures of an HIV virion and the cilia of an animal cell is that the glycoprotein structures are used for attachment, while the cilia are used to move fluids surrounding the cell.

The glycoprotein structures on an HIV virion and the cilia of an animal cell serve distinct functions crucial to their respective biological roles. In the case of HIV, the glycoproteins, notably gp120 and gp41, play a pivotal role in the initial stages of infection. These structures facilitate viral attachment to specific receptors on host cells, enabling the virus to enter and infect the host. Conversely, cilia on animal cells function as microscopic hair-like projections extending from the cell surface.

These structures are primarily involved in cellular locomotion and the movement of fluids surrounding the cell. By coordinated rhythmic beating, cilia contribute to tasks such as moving mucus in respiratory passages or facilitating the transport of eggs in the female reproductive tract. Thus, while glycoprotein structures aid in viral attachment, cilia serve as dynamic appendages for cellular movement and fluid transport.
