Re: Broadcast TV Fee. Pretty much everyone on cable tv pays the Broadcast TV fee, and it's not just particular to Comcast. Broadcast stations [your local stations] charge the cable companies fees to carry their programs. In turn, cable companies pass those fees along to the customers. All cable tiers carry the broadcast channels. So, basically, yes, you'll be paying that $5 Broadcast TV fee.
Growth factors are organized into three categories. Some bacteria (e.g. E. coli) do not require any growth factors: they can synthesize all essential purines, pyrimidines, amino acids and vitamins, starting with their carbon source, as part of their own intermediary metabolism.
Bacteria that contain bacteriochlorophyll do not use water as an electron donor and therefore do not produce oxygen. This is known as anoxygenic photosynthesis. Cyanobacteria perform photosynthesis using water as an electron donor in a similar manner to plants. This results in the production of oxygen and is known as oxygenic photosynthesis.
