Describe how the structure of a virus aids in its ability to infect cells.

Virulence factors of virus aids in its ability to infect cells.  

Explanation:

Virulence factors help pathogenic microbes to infect host cells by virulence mechanisms – invade host, cause and spread disease, evade the defense or immune mechanism of the host. These factors makes the virus to grow, replicate, and modify the host cells due to its toxicity.  

Viruses binds to the receptor protein of the host cell.

Different types of virulent factors are: invasion factors, adhesive or adherent factors, capsules, endo and exotoxins, etc.  

The virulence factors decides the severity and rate of spread of an infection

i think it’s c but i might be wrong. if i am let me know! have a good rest of your day as well!

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
