If you allowed 10 identical parallel Salmonella cultures to evolve for 10,000 generations under new growth conditions with very little nitrogen, the parallel cultures would
A. evolve identical adaptations to use the nitrogen source provided in the media.
B. not change or adapt very much over this small number of generations.
C. each accumulate different random mutations resulting in different adaptations to use the nitrogen in the media.
D. direct mutations to occur in nitrogen utilization and uptake genes in order to adapt rapidly to the culture conditions.
