Many farm animals grow a natural winter coat to help endure frigid temperatures, but their domestication brings a certain level of responsibility to the people who own them.
Freezing is a common method of food preservation that slows both food decay and the growth of micro-organisms. Besides the effect of lower temperatures on reaction rates, freezing makes water less available for bacteria growth. Freezing is a widely used method of food preservation. Freezing generally preserves flavours, smell and nutritional ...
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.
Frozen Planet is a 2011 British nature documentary series. It was produced as a co-production between the BBC Natural History Unit, Discovery Channel, Antena 3 Television S.A., ZDF, Skai tv and The Open University, in association with Discovery Channel Canada. [2]

Plants and animals endemic to snowbound areas develop ways to adapt. Among the adaptive mechanisms for plants are freeze-adaptive chemistry, [105] dormancy, seasonal dieback, survival of seeds; and for animals are hibernation, insulation, anti-freeze chemistry, storing food, drawing on reserves from within the body, and clustering for mutual heat.
Freeze brands are made for a variety of purposes. For example, they are used to indicate that an animal belongs to a particular herd, all members of which are marked with the same brand. They are also used to indicate via a unique pattern that an individual animal is a particular person's or ranch's property.
Water expands by 9% as it freezes. Occasionally the surface can freeze over except for a small hole; the continuing freezing and expansion of water that is below the surface ice then slowly pushes the remaining water up through the hole. Reaching very cold air, the edge of the extruded water freezes while remaining liquid in the center.
