Imagine there was a campaign to wipe out all bacteria. Why would this not be a good
idea? In your answer, include the terms amino acids, ammonia, nitrites, and nitrates as you
discuss the role of bacteria in the nitrogen cycle.

If all the bacteria are removed from the earth, all the organisms are negatively affected.

Explanation: There are also some beneficial bacteria which helps in the nitrogen fixation called Nitrogen fixing bacteria such as Cyanobacteria and Azotobactor. These bacteria fixes atmospheric nitrogen into ammonium and nitrates form because plants are unable to use the atmospheric nitrogen, it only use nitrogen in ammonia and nitrates form. Plants absorb nitrates and form amino acid.

. ph changes the ability of them he enzyme to dissolve in water.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
