Question

19. In summer, certain lizards have a low critical minimum temperature of 2.5ºC. In winter, these same lizards have a critical minimum temperature of -1.2ºC. The lizards do not freeze at this critical minimum temperature, even though this is below the freezing point for their blood. They are able to move under the snow while in this supercooled state at a temperature slightly above -1.2ºC. Hypothesize as to how the lizards are able to keep from freezing at temperatures below 0ºC.

Answer 1

They stay warmer under the snow and their metabolism slows down----like hibernating bears and other hibernating animals do.

This is just a guess....................... =)

Answer 2

They drink antifreeze in autumn...??
