When Polypeptides join together, they form protein. The term Polypeptide chain is used to define the combination of Polypeptides. They are joined together by the peptide bonds. These Polypeptides are chains of amino acids. When one or more Polypeptide chains joined together, that is the time when Protein was born. As we all know, protein is very essential to our body. Because protein helps our body to function well. Protein makes our cells function properly. Can you imagine our body without protein? Thanks to Polypeptides chains that are joined together to form Protein so our body can function well. </span>

Answer:
B. After clearcutting, plant uptake stopped and nitrogen accumulated in the soil.
Explanation: Clear cutting leaves the soil bare and allows for direct penetration of sunlight this increases the soil temperature which favors the activity of soil microrganism. This microrganism activity increase the production of ammonium and nitrate hence the increase in soil Nitrogen level. Clearcutting then allows for accumulation of Nitrogen produce due to removal of plant or forest tree that could use up the Nitrogen produced.
