About 80% of the air consists of nitrogen. Certain types of bacteria present in soil convert this nitrogen into nitrogen compounds, which can be used by plants. Plants absorb these compounds through their roots and use them to grow. When living organisms consume plants, the nitrogen products enter their bodies. Based on this description, arrange the subsystems in the order that nitrogen has moved through them. ​

How is ribosomal rna useful as a molecular clock? a. a large portion of the dna ring is not vital to structure or function, allowing it to accumulate neutral mutations. b. its rate of mutation increases over time as organisms continue to evolve and differentiate from each other. c. a slow mutation rate makes it useful for determining evolutionary relationships between ancient species. d. it is only found in select organisms, making it easier to compare relationships between species that have it.
