Answer:
Answer: an increase in the respiratory rate.
Explanation:
Negative feedback is considered as the major regulatory process or mechanism in living things to bring about physiological function.
It should be noted that in negative feedback, the end product of a certain process or activity in turn brings about the reduction of that same process.
In this case , according to negative feedback, sensory receptor discovered by the scientist which detects decreasing oxygen concentrations in the blood will in turn bring about an increase in the respiratory rate when stimulated. This activity will definitely results to increase in the concentration of oxygen in the blood.
