Bacteria have different oxygen requirements Bacteria obtain energy from many different sources How did so much diversity evolve in the absence of sexual reproduction? Bacteria exchange genetic material through conjugation Bacteria on and in the human body Benefits of bacteria In the environment, bacteria that obtain energy from inorganic molecules release forms of these molecules that are used by plants Nitrogen-fixing bacteria

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
