3 atoms (O3) Ozone is the triatomic form of oxygen. Oxygen isn’t the only thing we breathe, we also breathe nitrogen and a whole bunch of other gases. The difference between oxygen and ozone is ozone is o3 meaning it has 3 oxygen atoms instead of just one. I really hope this helped!
Mitochondra, the organelle, responsible for the conversion of the chemical energy stored in food into ATP (adenosine triphosphate-energy rich molecule). The cell easily utilize these molecules and perform all of its functions
It is important the entire scientific community uses the metric system rather than each country having its own system because when scientist are comparing or sharing results they wont have to do extra steps of converting to different measurements it will just be the same and less confusing.
