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.
After all, every cell in your body (except mature red blood cell, which have no nuclei, and egg cells) has the same DNA in its nucleus. Why would mitochondria need. The best story we have now is that mitochondria are actually the descendants of bacteria that hitched a ride in larger, more complex cells. Our cells, and those of plants, amoeba-type things, and fungi, are eukaryotic.. Bacterial cells are called prokaryotic.. They don't have nuclei, they are much smaller than our cells, and don't have organelles like our cells. Perhaps the tiny prokaryotes invaded early eukaryotes a long time ago (like 1.4 billion years ago) in order to absorb their food, acting like parasites.
