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.
Identify and describe different categories of microbes with requirements for growth with or without oxygen: obligate aerobe, obligate anaerobe, facultative anaerobe, aerotolerant anaerobe, microaerophile, and capnophile. Give examples of microorganisms for each category of growth requirements.
