Why do viral mutations pose such a threat to human health?
genes
Viruses are much smaller than bacteria.
deactivated particles of the flu virus
both A and B
viruses can survive while waiting to come in contact with a host to infect
Viruses mutate faster than the human immune system can build antibodies.
they cannot replicate without the organelles in a host cell
the host cell fills with new virus and bursts open
Charles Chamberland, a French microbiologist, invented a filter in 1884 that allowed for the separation of bacteria from viruses. His invention was a turning point in the study of viruses. What property of viruses allowed Chamberland’s filter to wo
