NEETZoologyBreathing and Exchange of Gases
Read the following Assertion and Reason and choose the correct option. Assertion: Increase in CO2 cannot be detected by the chemosensitive area adjacent to the rhythm centre Reason: Oxygen has significant roles in the regulation of rhythmic centre
Options
- ABoth Assertion and Reason are true and Reason is correct explanation of Assertion
- BBoth Assertion and Reason are true but Reason is not the correct explanation of Assertion
- CAssertion is true but the Reason is false
- DBoth Assertion are Reason are false
Correct answer
D. Both Assertion are Reason are false
Step-by-step solution
A chemosensitive area is situated adjacent to the rhythm centre which is highly sensitive to CO2 and hydrogen ions. Increase in these substances can activate this centre, which in turn can signal the rhythm centre to make necessary adjustments in the respiratory process by which these substances can be eliminated.
