Cold foods should be held at temperatures of 40°F (4°C) or below to prevent the growth of harmful bacteria. It’s important to regularly check and maintain this temperature, especially in commercial settings, to ensure food safety. Additionally, foods should be stored in appropriate refrigeration units to keep them consistently cold.
This phrase typically refers to being immobilized or trapped in a strong or firm hold due to ice or cold temperatures. It conveys a sense of being firmly held or restricted by the icy conditions, making movement or escape difficult.
The precipitation in the polar zone is generally low, with most areas receiving less than 10 inches of precipitation per year. This is due to the cold temperatures, which limit the amount of moisture that can be held in the air. Snowfall is the most common form of precipitation in the polar zone.
Seeds in dormancy do not require much. They need to be kept in a dry and cool environment to prevent germination. Some seeds may benefit from stratification (exposure to cold temperatures) to break dormancy and improve germination rates.
They are held together by hydrophobic interactions in which the hydrophilic 'heads' (phosphate group) of the phospholipid face outwards towards the aqueous environment while the hydrophobic 'tails' (long hydrocarbon chains of fatty acids) face inwards, away from the aqueous environment.
If we held a wire a on upper portion so it is not very hot and middle portion is too hot ,inner is cold
A "TCF" (time and temp. control food safety) is now being widely used as opposed to the "PHF"- (potentially hazardous foods) acronym. it is any foods that need constant temperature monitoring for safety. hot held foods 139 F. Minimum, cold held foods 41 F. or lower.
Hot foods should be held at a temperature of at least 140 degrees F. Cold foods (salads, sandwich spreads, dairy and mayo based) should be held at 40 degrees F or lower.
Food should be hot held at 135 F for no more than 4 hours. Food should be reheated to 165 F for at least 15 seconds before the 4 hour point is reached.

Generally, potentially hazardous foods should be stores at 40°F or below. Vacuum-packaged foods that require refrigeration should be stored at 38°F or below, due to concerns about Clostridium botulinum.
The term "time and temperature abuse" refers to the transport and storage of foods or when foods are "not cooked to the recommended minimum internal temperature, not held at the proper temperature, or not cooled or reheated properly". Temperature danger zone occurs between 41°F to 140°F. Prevention means keeping foods out of that danger zone.
Only the type of cold that you feel from low temperatures. You can not catch the infectious disease called the common cold from climbing mountains or from being cold. The common cold is caused by viruses that you catch from other people, it has nothing to do with cold weather. Check out the related questions in the related questions section for more about this long held belief/myth that you catch a cold from being in the cold. It is just a myth from before people knew about viruses.
Hold hot foods at 135 F degrees and check temp every 4 hours. At 4 hours, if temp has fallen below 135 degrees F, then throw it out. Do not reheat it. Do not eat it or let anyone else eat it.
somewhere cold
yes you can, providing you put it in the fridge, so bacteria dose not get to it.Do not defrost frozen meat and poultry products at room temperature. Keeping the products cold during defrosting is the key to preventing bacteria from growing.Always cook fresh meat and poultry products immediately after microwave defrosting. During microwave defrosting, random areas will sometimes begin to cook, creating temperatures easily high enough for harmful bacteria to thrive. To defrost meat or poultry products in cold water, do not remove original packaging. Be sure the package is airtight or put it into a leak-proof bag before submerging the product completely in cold water, changing the water every 30 minutes so that it continues to defrost. Note: Foods defrosted in the microwave or by the cold-water method should be cooked before refreezing because they may have been held at temperatures higher than 40 F. Wash all utensils, cutting surfaces and counters with hot, soapy water after contact with meat and poultry. If possible, use a separate cutting board for fresh meat and poultry products. Wash hands thoroughly in hot, soapy water before and after handling meat and other fresh foods. Keep fresh meat and meat juices away from other foods, both in the refrigerator and during preparation. Never place cooked foods on the same platter, board or tray that held fresh meats or poultry.

Polar Explorers prepared their food over a fire in tents. The Polar Explorers ate many of the same foods that are eaten today. The type of food that held up, had to remain fresh in the cold whether which was a positive for the location.
