true.

Explanation:

Tolerance is a term related to the use of medicines. It happens when your body, after taking the same medicine several times, develops a tolerance to the effect that that dose of medicine had on your body. As a result, you will need to take ever higher doses for the medicine to take effect on your body.

With that, we can say that it is true that tolerance requires you to use the medication to achieve the same high or medical effect.

enzyme active site and substrate specificity

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
