2. Why did the scientists find Henrietta’s cells so important? (What was different about Henrietta’s cells than other cells scientists had used?)

Henrietta's cells never died/they kept replicating/they are immortal cells

Explanation:

Cells typically die after so many replication cycles, her cells did not. They are considered  immortal cells. They have an over active telomerase that rebuilds the telomeres after each division. Therefore these cells do not age and can continue replicating

i believe the answer is a or 1

answers are:

lysogenic     viral dna merges with host cell dna

lysogenic     no symptoms

lytic               viral dna takes over

lysogenic     virus does not destroy host cell

lytic               virus destroys host cell

lytic               induces symptoms of viral infection

lysogenic       cell reproduces and spreads provirus
