Title: Bacteria and Archaea
Description: Biology 102:Bacteria and archaea. Highlighting both the similarities and differences of bacteria and archaea, you will discover: how they interact with the human body, the environment, and how their DNA is transmitted. While necessary for life for many reasons and found all over the human body, they can also cause diseases. With some talk of antibiotics, antibiotic resistance and going over the nitrogen cycle the entire chapter will be thoroughly covered
