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.

H1N1 flu is a highly contagious viral infection caused by the influenza A (H1N1) virus. The symptoms of H1N1 flu are listed in the box below. An antiviral agent administered within 48 hours of the appearance of symptoms can reduce the severity of the illness.
Why is it important to administer an antiviral agent to an infected person within 48 hours of the appearance of symptoms?
The H1N1 virus is dormant in cells.
The H1N1 virus replicates quickly
The H1N1 virus does not mutate.
The H1N1 virus is transmitted through a vector host, such as a mosquito.

A person infected with the human immunodeficiency virus (HIV) may not have any symptoms for a period of time. During this period the virus affects the body by doing which of the following?
The virus produces toxins that weaken immune cells and prevent them from reproducing.
The virus damages immune cells while using their machinery to produce copies of itself.
The virus uses nutrients meant for immune cells to fuel its own cellular respiration.
The virus changes the identity of the nucleotides of immune cells to prevent the immune system from functioning normally.

Severe acute respiratory syndrome (SARS) is an illness caused by a coronavirus. Symptoms including a high fever, headaches, and body aches typically occur two to seven days after infection by the virus. SARS is more serious in elderly patients. This information suggests that the reproductive cycle of the SARS virus is —
lysogenic, because the virus is a coronavirus
lytic, because the virus causes respiratory illness
lysogenic, because the virus primarily affects older people
lytic, because of the quick onset of symptoms after infection
