Answers (1)
Correct Answer is Option (2) Both assertion and reason are true, but the reason is not the correct explanation of the assertion.
The assertion that frogs have a three-chambered heart and a double circulatory system is true. However, the reason that the double circulatory system allows for efficient oxygen delivery to the tissues of the body is not entirely accurate in the case of frogs. While the double circulatory system is generally more efficient in delivering oxygen to the tissues, frogs also have a unique respiratory system that allows them to absorb oxygen directly through their skin. This means that the circulatory system in frogs is adapted to transport not only oxygen but also carbon dioxide and other metabolic wastes.
Therefore, while the double circulatory system is important for efficient oxygen delivery, it is not the only reason for its presence in frogs.
