Question

A(n) ________ in blood CO2 levels causes a(n) _________ in blood pH, resulting in a(n) __________ in breathing rate.

a) Increase, increase, decrease
b) Decrease, increase, increase
c) Increase, decrease, increase
d) Decrease, decrease, decrease

Answer 1

I believe it is C, Increase, decrease, increase.

When there is an increase in Co2 your blood PH is going to decrease, when there is Co2 in your body it’s going to cause you to take a breath to try and level it out with oxygen.
Increasing the concentration of carbon dioxide in the blood therefore results in more H+ ions and a lower pH.
You can only imagine how it’s going to be when there is too much Co2. Your body is going to panic and immediately try and breathe more and more, because your body is trying to level itself out. Which could also cause hyperventilation which could cause you to pass out.

Answer 2

a) Increase, increase, decrease. An increase in blood CO2 levels causes a decrease in blood pH, resulting in an increase in breathing rate.

Step-by-step explanation:

An increase in blood CO2 levels causes a decrease in blood pH, resulting in an increase in breathing rate. Therefore, the correct option is a) Increase, decrease, increase.
