Question

You are setting up your own lab, where you plan to study proteobacteria. You have narrowed your research focus and decided that you are most interested in the role of proteobacteria in the global nitrogen cycle. Which species of proteobacteria should your researchers study?

Check all that apply.
a. Alphab. Betac. Epsilond. Deltae. Gamma

Answer 1

-Alphaproteobacteria

-Betaproteobacteria

Step-by-step explanation:

• Proteobacteria are gram-negative bacteria that can either be pathogenic or free-living parasitic in nature.
• Several classes fall under the category of proteobacteria, and two of them are alphaproteobacteria and beta proteobacteria.
• Both Alphaproteobacteria and Betaproteobacteriaare are the ones that play an important role in nitrogen fixation and since according to the question the research is focused studying the role of proteobacteria in the global nitrogen cycle, it is wise to choose these two bacterial classes.
