Once DNA was shown to be the primary genetic material of life, a race among scientists took place to work out its structure. Which concept came from studying the amounts of each DNA base in different organisms?

the correct answer: the index of refraction of the second medium is lower i tried this persons answer and it was wrong this person is lying

yes it is weird but true

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.
