The transformation of ammonia (nh3) into nitrate (no3) is mostly performed by certain bacteria. this process is known as…
a. denitrification
b. nitrification
c. ammonification
d. nitrogen fixation
e. nitrogen assimilation

b. Nitrification

Explanation:

Nitrifying bacteria are present in the soil that help in the oxidation process of ammonia that liberates the nitrite (NO2-) and nitrate (NO3-) compounds. These resulting compounds are captured by plants and this process is called nitrification. In the nitrification stage there are two chemical processes. That are:

• Nitrous: is the oxidation of ammonia (NH3) that results in the nitrite chemical compound (NO2-).

• Nitration: It is the oxidation of ammonia (NH3) that results in nitrate (NO3-).

you must remain stopped until the stop signal is retracted and the red lights are turned off. approaching traffic in the opposite roadway of a divided highway shall not be required to stop, even if the school bus has the stop-arm extended and the alternately flashing warning signal lamps on.

spiders belong to a group of arachnids.

arachnids have the following traits :

they have two body parts.

they have eight legs unlike insects which have 6 legs.

they have no wings.

these traits distinguish them from insects.

the information that antonio is doubting us the statement that spiders differences are as a result of being first to evolve.

this is because the evolution of one species is independent of the other species.
