In order to reproduce, what does a virus need?

Viruses require a favorable environment free from stressors

Viruses require the host cell's DNA from the nucleus

Viruses require the host cell's ribosomes and active metabolism

Viruses require at least 40 minutes in order to copy the endoplasmic reticulum.

A corona virus, which causes disease in humans, tries to enter a plant cell - but cannot get in. Why not?

The glycoproteins (keys) on the virus do not match the plant cell.

The plant cell cannot get diseases like human cells can.

The plant cell must be a different size than the animal cell.

The plant cell has does not have a cell membrane to protect it.

Any virus, such as coronavirus, can infect any living thing. It does not matter what kind of cell they are trying to infect.

False, the glycoprotein keys must fit into the receptor on the outside of the host cell like a lock and key. Viruses are limited to a host range.

True, all a virus needs to reproduce is a host cell, it does not matter what kind of host cell.

True, viruses are universal and have matching structures common to all eukaryotic cells.

False, viruses cannot infect cells because they are not living and do not respond to stimuli.

The projections on the surface of this virus allow the virus to ---

attach to a host cell

move inside a host cell

control a host cells's DNA

signal other viruses to infect a host cell

Nødvendig

What role do the glycoproteins found on the outside of the virus play?

To attach and unlock the host cell

To allow for locomotion (movement)

To push the host cell away

A diagram of an HIV infection is shown.
Which conclusion about the HIV infection of a host cell is best supported by the diagram?

It requires carbon dioxide.

It relies on the host cell to reproduce.

It takes place outside of living cells.

It involves the process of meiosis.

The West Nile virus is a single-stranded RNA virus spread by mosquitos. Symptoms of severe illness include high fever, headache, neck stiffness, muscle weakness, vision loss, numbness, and paralysis. However, 8 out of 10 people do not feel any symptoms at all, and doctors claim that West Nile Virus is not contagious.
Which of the following best describes why someone cannot give West Nile Virus to anyone else?

West Nile Virus is only spread through contact with infected particles.

West Nile Virus is only spread through contaminated food sources.

West Nile Virus requires a mosquito host to spread the virus.

West Nile Virus does not affect healthy individuals.
