Have a few rare organelles but no nucleus have a permeable cell well, most have bacterial flagella Build organic compounds by photosynthesis “self-feeders” sunlight for energy, carbon dioxide as their carbon source When it nearly has doubled it divides in two. Each daughter cell inherits a single bacterial chromosome Bacteria that causes a disease; Streptacocal Live in mammalian gut- make vitamin K, helps digest fat, keeps food bourne pathogens in check Causes nitrogen- fixing nodules to form on roots of peas Methane makers Known as the 3 rd domain, resemble the first cells on earth. Most like Methanogens, extreme halophiles. Poison, protein coat surrounding a nucleic acid core; can’t reproduce itself, use host to reproduce. Viral DNA is integrated into the hosts chromosome.

    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.
