It is known that frogs at low temperatures fall into a state of seasonal numbness, and when the temperature rises, they come back to life. Explain what physiological features allow amphibians to survive the cold season and lower temperatures below 0 ° C.

1. The metabolism decreases sharply, oxygen absorption is reduced by 2–3 times, and the number of respiratory movements and contractions of the heart are reduced.
2. In vital organs, the water content decreases and the concentration of glucose and other substances that prevent freezing of cells increases.
3. The conductivity and excitability of the nerve pathways is reduced.
