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.
The immune system helps guard against infection, protect from UV radiation, and regulate body temperature.

Cancer is caused by a defective gene due to mutations. CRISPR-Cas9 tools can be used to edit out these parts of the gene. The tool can snip out and replace a section of DNA with a given DNA. The tool is a harnessed mechanism from bacteria that is a mechanism to identify foreign genetic material such as that of bacteriophages and destroy them.
