Answer:
Carbon convert into methane, Nitrogen converts into Ammonia and Sulfur converts into hydrogen sulfide gas
Explanation:
As the flow time in a wastewater treatment plant increase the color of waste water converts from grey to black as the condition becomes more anaerobic and flow becomes more septic. In such scenario if more waste water is added the sulfur and nitrogen extracts from the waste are converted into ammonia and hydrogen sulfide. Carbon is present in the form of organic waste and in the absence of oxygen it gets converted into methane gas. However , in presence of oxygen this carbon is released as carbon dioxide.

Answer:
Correct Answer: D. Answers A and C.
Explanation:
The other guy on this question was incorrect, i failed that question so here is the anwser.
Answer:
A. 25 °C, 30 °C, 35 °C, 40 °C, 45 °C
Explanation:
Each enzyme has a temperature at which it works best. In humans and many animals, that temperature is around body temperature (37 °C or 98.6 °F). Most enzymes are denatured and work poorly at 40 °C (104 °F).
That automatically eliminates Option B.
I would pick a temperature close to 37 °C (98.6 °F) and temperatures at intervals above and below that.
Option D is wrong because it includes no temperatures above body temperature.
Option C is wrong, because it includes temperatures of 45 °C and 55 °C, at which the enzymes will be denatured.
That leaves Option A as the best answer. It includes only one temperature above 40 °C.
