Difference between nitrification and dentrification
Explanation:
Nitrification and denitrification are part of the nitrogen cycle
Nitrification is the process of conversion of ammonium to nitrate by nitrifying bacteria like Nitrobacter and Nitrosomonas
Denitrification is the process of reduction of nitrate to nitrogen gas by denitrifying bacteria like Pseudomonos, Lactobacillus etc.
Nitrifying bacteria are autotrophs and grows slowly and need aerobic condition. Denitrifying bacteria are hetertrophs and grows rapidly and need anaerobic conditions.
Nitrification requires a pH of about 6.5 to 8.0; denitrification takes place at 7.0 to 8.5
Nitrification provides soluble nitrates readily available in the soil to be easily absorbed by the roots.
Denitrification processes are used in wastewater or effluent treatment plants.
Answer:
A. Thermal Oxidizer.
Explanation:
It helps to destroy hazardous air pollutants and volatile organic compounds at a high temperature and releases them into the atmosphere.

Newton's second law can be demonstrated by something very massive (high mass) that’s changing speed very slowly (low acceleration) and something very small (low mass) that’s changing speed very quickly (high acceleration. Thus, both the options A and B are correct.
<h3>What is Newton's second law?</h3>
According to newton second law of motion force is always equal to rate change of momentum.
So, Force basically depend on two factor i.e mass and velocity
In first case if mass is constant and velocity is variable then
Force = mass × acceleration.
And if mass is variable and velocity is constant then it's called thrust force
Thrust force = Rate change of mass × velocity.
S.I unit of mass is Newton.
Therefore, Newton's second law can be demonstrated by something very massive (high mass) that’s changing speed very slowly (low acceleration) and something very small (low mass) that’s changing speed very quickly (high acceleration. Thus, both the options A and B are correct.

<em>If the question looks like the picture below the the answer and the explaining is below.</em>
Answer:
D. At a rift valley the crust splits allowing basaltic magma to flow out without the force of a volcanos.
Explanation:
A. is a an illustration of a mid Atlantic ridge. Underseas volcanos form along the mid Atlantic and other Mid Ocean ridges. Some like in Iceland reach the surface.
B. Is an illustration of a hot spot volcano. These types of volcanos have formed the Hawaii islands. The island of Hawaii has an active volcano due to the action of a hot spot.
C. Is an illustration of a subduction zone. The heat and pressure that results from the ocean plate being pushed and pulled under a continental plate results in volcanos. Mt. St Helens is an example of volcano that results from a subduction zone.
D. is the correct answer, In a rift valley the magma can flow out through the break in the crust without forming a volcano. Western Oregon has vast lava beds of basaltic lava. There are no volcanos that were the source of these horizontal layers of lava.
