At least six major areas of cryobiology can be identified: 1) study of cold-adaptation of microorganisms, plants (cold hardiness), and animals, both invertebrates and vertebrates (including hibernation), 2) cryopreservation of cells, tissues, gametes, and embryos of animal and human origin for (medical) purposes of long-term storage by cooling to temperatures below the freezing point of water.
Plants that originated in the tropics, like tomato or maize, don't go through cold hardening and are unable to survive freezing temperatures. [3] The plant starts the adaptation by exposure to cold yet still not freezing temperatures. The process can be divided into three steps.
The best cat breeds for cold climates are well worth considering if you live in an area where the temperatures drop over the winter months. With many cats originating in countries known for having ...
Freezing temperatures curb the spoiling effect of microorganisms in food, but can also preserve some pathogens unharmed for long periods of time. Freezing kills some microorganisms by physical trauma, others are sublethally injured by freezing, and may recover to become infectious. [13]
Cats have existed for millions of years, but some are more likely to live longer than others. From Bengals to Siamese, these kitties may live for decades. 15 Cat Breeds That Live the Longest ...
While some frogs hibernate underground or in water, body temperatures still drop to −5 to −7 °C, causing them to freeze. The wood frog (Lithobates sylvaticus) can withstand repeated freezing, during which about 65% of its extracellular fluid is converted to ice. [58]

Various patterns of behavior enable certain ectotherms to regulate body temperature to a useful extent. To warm up, reptiles and many insects find sunny places and adopt positions that maximise their exposure; at harmfully high temperatures they seek shade or cooler water. In cold weather, honey bees huddle together to retain heat.
