a. both parents were heterozygous.
b. both parents were homozygous.

the electromagnetic energy from the sun arrives in the form of visible and invisible light.

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
