It is known that frogs at low temperatures fall into a state of seasonal numbness, and when the temperature rises, they revive again. Explain what physiological characteristics allow amphibians to survive the cold season and the temperature drop below 0 C.

Cold-blooded animals do not have special organs and systems for regulating and maintaining a constant body temperature. Therefore, the onset of cold weather can be dangerous for them. Cold-blooded animals, even before the onset of cold weather, hide where the temperature will not be critical. If the cells begin to freeze, it will destroy them and lead the body to death. Also, animals accumulate special fatty acids in their cells, which work as antifreeze and prevent water from crystallizing.
