Answer:
c)negative feedback, because the body’s responses counteract the stressor
Explanation:
We know that during exercise or extreme physical activity, the energy requirements are not only met by aerobic respiration but also an-aerobic respiration in which glucose is converted into lactic acid along with CO2.
How negative feedback works:
In our body, the negative feedback mechanism works by adjusting the output of a process. Now, during exercise when there is an increased demand of oxygen in our body, the homeostatic set points of our body for blood pressure and heart rate are reset.
When CO2 is increased,it accumulates in the body and decreases pH, why? Because CO2 is acidic.
So, we know that our body needs pH 7.35 to 7.45 to perform all physiological processes normally. Therefore, during exercise, chemoreceptors of our body detect the pH change and send the signals to our brain for increasing the rate of respiration of lungs. So body, responds by increasing the breathing out of excess CO2 rapidly and the pH is maintained.
This is negative feedback and body's response to counteract the stress.
Hope it helps! :)

Invasive species cause more damage than some pollutants. Almost half of the native species in America are endangered because of invasive species. Compared to other threats to biodiversity, invasive introduced species rank second only to habitat destruction, such as forest clearing.
