I have seen nitrogen fixation in three heterotrophs, but cannot detect any nitrogenase in their genomes. Are there any alternative pathways that I can look into that may provide information about the way the heterotrophs are fixing nitrogen?
I have the following equation, Eating choice (Yes/No)~ Box type (A/B/C). So the question is whether a certain box type affects eating choice in groups of dogs. The eating choice of each member in...
