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.
In order for some bacteria to grow, they need oxygen. These bacteria are called aerobic or aerobes.. Aerobic bacteria need oxygen to yield energy for growth. Most spoilage bacteria, molds, and yeast require oxygen to grow. Some bacteria grow in oxygen-free environments and are called anaerobic or anaerobes..
