I believe this would be the food chain, but could also very well be how advanced the human brain is. Hope this helped!
False. Nuclear fission or whatever the reactions are called creates high amounts of radiation, which are dangerous, especially if around for a long time Nuclear energy is VERY good though.
A nucleotide or a nucleic acid either one :)
It is a true statement. We do this with tomatato plants all the time. If you have ever looked closely at a tomatato plant you will notice tiny hairs on it, each hair can grow a new root system. So I cut it off then place it in a grow seed tray with some support and it grows a whole new plant. You do have to remove the leaves except the very top ones say 15-20 leaves should be left on the plant you want a bare stem up to that. Also works witha variety of ivy plants.
