С Read the following sentence from the introduction (paragraphs 1-4).
"That's because cold and flu viruses, despite their ferocity inside our
warm bodies, are structurally wimpy and cannot bear the harsh
conditions of the dry, outside world."
Which sentence from the article BEST supports this idea?
o Flu viruses and many cold viruses also have a viral envelope, meaning
the capsid is covered by two layers of lipids similar to the cell
membranes found on organisms.
Viruses outside the body can be better described as either infectious
or identifiable - meaning the genetic material that was once inside
the virus can be detected via a lab technique like polymerase chain
reaction, or PCR
Cold and flu viruses' rapid decrease in viability outside the body is
thanks to three main factors: their enveloped structure, environmental
conditions and how much our mucus surrounds it after a sneeze.
But on the plus side, Greatorex said, the more mucus a friend or co-
worker sneezes, the shorter distance it will travel because of its
increased weight and size
