Answer:
He can deduce that The pO2 of her cells is less than or equal to 200 mmHg.
Explanation:
Partial pressure of oxygen(pO2) measures the amount of gaseous oxygen dissolved in the blood. It purposes to measure the effectiveness of the lungs in pulling oxygen from the atmosphere to the lungs.
In the incubator where the gases levels are carefully regulated, a pO2 of 200mmHg on the incubator deduces that the pO2 of her cells is equal or less than 200mmHg.
So that it can sustain different life that requires different environments. Angler fish, for example, require a dark and cold environment to thrive while tuna require a light and warm environment.
Answer:
Early cyanobacteria in stromatolites are thought to be responsible for increasing the amount of oxygen in the primeval Earth's atmosphere through their continuing photosynthesis. They were the first known organisms to photosynthesize and produce free oxygen.
Hope this helps!!!
