Pictured here is the nitrogen cycle. The organisms that are responsible for
nitrification are most likely...

Option A, Bacteria

Explanation:

Nitrifying bacteria is a group of aerobic bacteria that converts ammonia in soil into nitrates so that it can be easily taken up by the plants. So basically, in this entire conversion bacteria’s of two distinct group are used – a) bacteria that convert ammonia to nitrites (such as Nitrosomonas, Nitrosospira, Nitrosococcus, and Nitrosolobus ); and b) bacteria that converts nitrites to nitrates

Hence, option A is correct

b is dominant over the allele for the white fur.

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
