|
What are the two basic parts of a virus? |
Protein Coat and Nucleic Acid
|
|
Explain the steps of the lytic cycle in order |

|
How do we treat bacterial infections? |
Antibiotics |
|
How can we prevent viral and bacterial infections? |
By washing your hands and any wounds you may get. |
|
Bacteria are seen under the microscope as three shapes: Coccus, bacillus, sprillum - Describe these shapes. |
Coccus - spherical shaped Bacillus- rod shaped Sprillum - spiral shaped |
|
How are viruses not like bacteria? |
viruses reproduce through the lytic cycle-inside the cell (host)
