proteins
Viruses are composed of the following particles except:
protein
RNA
lipid bilayer

How far can droplets from your airways travel when you cough or sneeze?
1 foot
3 feet
5 feet
7 - 30 feet
Which is the best explanation of why rough surfaces inactivate viruses?
Rough surfaces create a lot of hydrogen bonds and can pull the virus apart.
Rough surfaces do not create much of a hydrogen bond with the virus, so the virus stays together.

twice a day
once per hour
every 30 minutes
every 3 - 5 minutes
Which surface would keep a virus the most stable?
skin

falls apart
multiplies
is stable
strengthens
