Students investigated the effect of acid rain on photosynthesis. Several plants were given water with a pH of 4 each day for two months. The results showed that the plants had a reduced rate of photosynthesis.
How did the acidic water most likely reduce the plants' rate of photosynthesis?

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

it depends on how much it could carry.
