Only answer if you know it?

If there is a 22 nucleotide base sequence difference for a gene found in both humans and penguins, what is the estimated mutation rate for that gene (your answer should be in #of mutations per million years). Use the phylogenic tree shown and SHOW YOUR WORK.

it is prolly d and c and f

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
