Question:
Assertion (A): Ascaris lumbricoides is a facultative anaerobe.
Reason (R): Ascaris performs either aerobic or anaerobic respiration depending on availability of oxygen.
Assertion (A): Ascaris lumbricoides is a facultative anaerobe.
Reason (R): Ascaris performs either aerobic or anaerobic respiration depending on availability of oxygen.
Reason (R): Ascaris performs either aerobic or anaerobic respiration depending on availability of oxygen.
Show Hint
Facultative anaerobes = survive in both oxygen-rich and oxygen-poor environments.

- Both A and R are true and R is the correct explanation of A.
- Both A and R are true but R is not the correct explanation of A.
- A is true and R is false.
- A is false and R is true.
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Ascaris can survive in both aerobic and anaerobic conditions due to its facultative anaerobic nature. It switches between aerobic and anaerobic modes of respiration based on oxygen availability.
