Answer:
Hope ur referring to the nitrogen cycle, but here goes: basically, u can start anywhere in the nitrogen cycle to describe what happens to that nitrogen. For instance, you can start in the atmosphere. Nitrogen makes up a considerable amount of the Earth's atmosphere. This nitrogen is fixated by nitrogen-fixating bacteria and is converted into ammonia, a form that can be absorbed by organisms. This enters into the ecosystem. When plants/animals that have nitrogen in their systems die, the nitrogen is returned into the soil. Some plants cannot absorb ammonia however. So, a process known as nitrification also takes place. This is when ammonia is then converted into substances known as nitrites and nitrates, which are then absorbed. Lastly, denitrifying prokaryotes convert nitrates back into atmospheric nitrogen. Thus is the cycle.

Answer:
Group 4
Explanation:
The control group in this case would be those students in group 4.
<u>The control group during an experiment is a group that does not receive the treatment administered to other groups and as such used as a standard for measuring the effects of the treatment on other groups. </u>Whatever differences that exist between the control group and the various treatment groups is attributed to be as a result of the treatment administered to the groups.
In this case, group 4 only used warm water for washing their hands instead of the hand sanitizer/soap used by the other groups. Whatever differences found out in the bacterial count in their respective culture swabs can be attributed to the effects of the hand sanitizer/soap.
