A typical virus consists of glycoproteins on the outside (keys) that match receptor proteins (locks) on host cells.
The role of these glycoproteins is to…

Used for locomotion (movement) by the virus.

Allow the virus to talk to other viruses.

Attach to cells that have matching receptors.

Allow the virus to create ribosomes.

In 1898, Friedrich Loeffler and Paul Frosch found evidence that the cause of the highly contagious "hoof-and-mouth" disease in livestock was a microscopic infectious particle. It was discovered that this particle requires a host cell to reproduce.
Which pathogen is most likely responsible for causing "hoof-and-mouth" disease in livestock?

A protist, because it is microscopic.

A virus, because it requires a host cell to reproduce.

A bacteria, because it is contagious.

A fungus, because it infects livestock.

Which of these describes a difference between viruses and cells?

Cells reproduce independently, and viruses require a host to reproduce.

Cells contain protein, and viruses contain only carbohydrates.

Viruses have membranes made of proteins, and cells have membranes made of nucleic acid.

Viruses have flagella, and cells have only cilia.

Models of the human immunodeficiency virus (HIV) and an animal cell are shown below.
What is the difference in function of the glycoprotein structures of an HIV virus and the cilia (hairs) of an animal cell?

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 to move fluids surrounding the cell.

The glycoprotein structures are used for attachment, and the cilia are used for locomotion (movement).

The glycoprotein structures are used to obtain nutrients, and the cilia are used to secrete proteins.

COVID-19 is an illness caused by the coronavirus "SARS-CoV-2". Symptoms include: high fever, dry cough, loss of taste and smell, shortness of breath, fatigue, headaches, and body aches. These symptoms typically occur within two to seven days after infection by the virus.
This information suggests that SARS-CoV-2 reproduces by the…

Lytic cycle, because the virus causes respiratory illness.

Lysogenic cycle, because symptoms occur quickly after being infected.

Lytic cycle, because the symptoms occur quickly after being infected.

Lysogenic cycle, because the virus is a coronavirus.

A person infected with HIV may not have any symptoms for an extended period of time, sometimes up to 10 years after initial exposure to the virus. However, a person with the Ebola virus shows symptoms within days after exposure to the virus.
What can you conclude about the life cycles of these two viruses?

HIV and Ebola both can be cured with antibiotics.

HIV replicates by the lysogenic cycle and Ebola by the lytic cycle.

HIV replicates by the lytic cycle and Ebola by the lysogenic cycle.

HIV and Ebola go through the same cycle for reproduction.

Tamiflu is often prescribed to patients that have been diagnosed with the flu within 48 hours of their first symptoms. Tamiflu works by slowing down viral replication by preventing the flu virus from entering the host cell.
Based on this information, which of the following would best explain how Tamiflu works?

Tamiflu stops the replication of viral DNA by the host cell's enzymes.

Tamiflu prevents the merging (joining) of viral DNA and host cell DNA.

Tamiflu shuts down the host cell's ribosomes, preventing the synthesis of the proteins needed to make the virus.

Tamiflu blocks the receptors on the outside of the host cell so that the viral glycoproteins do not attach.
