Do you have any particular hunches? For example, lysogenic infection is when a host cell into making a lot of copies of the virus that infected it. So many that it gets full and bursts (lyses in scientific parlance) and releases all those new virus particles to go off and infect other cells. Obviously this kills the host cell (think about a popped water balloon) so it does not go on for many generations.

1. True ----Availability of water, fresh air, land, and temperature between -10 to 50 degree celcius. 
2.True----is one of two methods of viral reproduction (the ... being expressed confers an immunity for the host bacteria from lytic infection .
3.True----If bacteria multiply and release toxins (poisons) into the blood it can cause serious illness
4.False they uses cilia
