Quizplus · Accepted Answer

At temperatures below 0°C (or 273.15K), water molecules freeze and form ice crystals, which can damage or disrupt the structure of biological cells and molecules. Organisms have evolved mechanisms to survive in different temperature ranges, but most cannot withstand extreme subzero temperatures.
