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.
1 Organisms that need only CO2 as a carbon source are autotrophs. 2  Organisms that require at least one organic nutrientâsuch as glucoseâas a carbon source are heterotrophs.  These categories of energy source and carbon source can be combined to group prokaryotes according to four major modes of nutrition.
