A scientist discovers a new species of marine bacteria that do not require oxygen to survive. In fact, dissolved oxygen in the water is actually toxic to these bacteria. Predict what region of the ocean this species would most likely inhabit, and select the best explanation.
A.)Deep becasue there is less oxygen exchange
B.)Deep because there are more oxygen-containing compounds
C.)Shallow because more oxygen is produced
D.)Shallow becasue low pressure increases dissolved gas
