Answer:
Explanation:
Sickle cell anemia is a result of the point mutation, and in a change in just one nucleotide in a gene for hemoglobin. This mutation will cause the hemoglobin in the red blood cells to distort to a sickle shape when deoxygenated. "The sickle-shaped blood cells clog in the capillaries, cutting off circulation."
This process is called precipitation. Still, the process is formation of liquid from gas then will go down the surface.
The tricky part of this question is the combination of nitrogen and water, as this process is not nitrification. Nitrification is the conversion of ammonia to nitrous or nitric oxide by nitrifying bacteria. Transpiration if evaporation of water through plant leaves. Respiration is the conversion of oxygen to carbon dioxide by organisms.
