cathy read about whales and learned that the average length of a blue whale is 80 feet. she also read that they can grow to be 94 feet long. cathy wondered if the length of the blue whale is genetic.
if two whales of maximum length mated, the selection in this case would be
no options

It would be maximum length because both parents are passing on those genes.

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.
