Questions
2.) Viruses can get entry into a cell many ways. They can enter through endocytosis, when the virus tricks the host cell into thinking it is harmless so the membrane lets the virus in. Another way is membrane fusion, which is when the virus attaches to the host cell and fuses with the membrane. Lastly, a virus can get in through genetic injection. This is when the virus attaches to the cell and injects its DNA/RNA into the cell.
3.) Tobacco plants can not be infected with the ebola virus because they have a unique trait where they can latch on to the virus and immediately activate an immune response against it.
4.) HIV: T-helper cells
Ebola: Fibroblasts of any type, most commonly mononuclear phagocytes
Marburg: Endothelial cells
Measles: Polarized Epithelial cells
Herpes: Neuronal and skin cells
5.) If you have the flu, your doctor will not provide you with antibiotics because antibiotics are medications that fight infections caused by bacteria, but the flu is caused by a virus. Taking antibiotics when you have a virus can hurt you instead of making you better.
6.) A person infected with a virus like HIV may not show symptoms because HIV reproduces via the lysogenic cycle. In this cycle a virus spreads through its host VERY slowly. The host can have a virus like HIV and not exhibit symptoms or know for months to years.
