Question

Quizplus · Accepted Answer

Amphibians are known for their ability to absorb oxygen through their skin, which is a significant part of their respiratory system. This skin must remain moist to facilitate gas exchange effectively. The statement about losing "CO₂" through their gills seems to be a typographical error, but it likely refers to losing carbon dioxide (CO2) through their skin or gills, which is a common process in amphibians.
