4B: Why are bacteria affected by antibiotics but not viruses? What is the difference between them that separates them from the potency of antibiotics?
Here is an image of antibiotics that humans take
Here is an image of a virus attaching to a host and breaking through its membrane
Here is a diagram of what happens to bacteria when there is antibiotics
4B: How do viruses reproduce?
4C: Why are viruses so deadly?
Viruses may be microscopic, but they are still very lethal. Different viruses have killed millions of people worldwide and take no mercy on anyone. There is not any antibiotic that can kill a virus and that is part of the reason why it is so deadly. Viruses don't have a cell wall and a vast majority of antibiotics attack the cell wall so it doesn't affect them. This helps the viruses become more lethal because they are not able to be killed by drugs so they are able to survive in the body for a long time. Another reason why viruses are so deadly is because they are able to go inside cells and affect them. For example, when viruses reproduce, they insert themselves inside the host cell to use their parts in order to reproduce. This also affects the cells because usually when this happens, the host cell dies. These two factors and many more can cause for viruses to become extra lethal and give them the edge that they need in order overrule a system.
