In codominance, the phenotypes produced by both alleles are clearly expressed. A typical example showing codominance is the ABO blood group system. For instance, a person having A allele and B allele will have a blood type AB because both the A and B alleles are codominant with each other.
Nitrogen is a limiting plant nutrient because the bulk of the available nitrogen in the atmosphere is not usable by plants.
Plants are not able to make use of the nitrogen in the atmosphere directly. Atmospheric nitrogen needs to be converted into usable forms before it can be accessed by plants.
The conversion of atmospheric nitrogen to usable form by plants is known as nitrogen fixation and this is achievable by the activities of certain bacteria.

Answer:
1. Óxidos são compostos binários formados pela reação do oxigênio com outros elementos.
2. Além disso, a tonificação também pode ficar feia e ocorrer em tons de preto e marrom. Nos casos mais graves, a tonalidade pode se transformar em corrosão e causar danos permanentes à superfície da moeda. Nos piores casos, a corrosão pode tornar a superfície da moeda porosa de tal forma que parece que foi tratada com jato de areia
3. (por exemplo, Li2O). Os óxidos são compostos binários de oxigênio com outro elemento, por exemplo, CO2, SO2, CaO, CO, ZnO, BaO2, H2O, etc. Estes são denominados como óxidos porque aqui, o oxigênio está em combinação com apenas um elemento.
