Name: 

Viruses

 

 

True/False
Indicate whether the sentence or statement is true or false.
1.
Although viruses do not consist of cells, biologists consider them to be living because they are capable of reproduction.
2.
Some viruses have a membranous envelope surrounding the protein coat that helps them gain entry into host cells.
3.
Viruses consist of RNA or DNA surrounded by a coat of protein.
4.
Prions are the smallest known particles that are able to replicate.
5.
A virus can only reproduce by controlling a cell.
6.
Once a virus enters either a lytic or a lysogenic cycle, it cannot change to the opposite type of cycle.
7.
Prophages and proviruses can both enter lytic cycles and destroy host cells.
8.
People can contract the influenza virus more than once because the virus tends to mutate rapidly, avoiding the actions of the immune system.
