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. Aerobes-oxygen required. 2. obligate anaerobes-growth in absence of Oxygen 3.facultative anaerobes-growth best where most oxygen is present but occurs through. With/without O2 4.microaerophiles-growth where a low concentration of oxygen is. 5.aerotolerant-equal growth with/without O2. Oxygen has no effect.
