Exposed to sunlight:
At this point of the experiment we see an increment in the oxygen and we also appreciate some algae that are growing at this part.
In this section we see an increase of the orange zone , that its caused by the bacterium and the production of sulfurous.
Also we can see some differences between the zone that is directly exposed to the sunligth from the other one :
We appreciate here that there isn't the orange zone that was mentioned before.
At the bottom part of the bottle we can see a black zone that
its caused by the sulfurous that is precipitating.
Without sunlight:
In this one we havent seen any changes at the top and middle part, we appreciated a increase of the bottom part caused by the sulfurous that is precipitating.
