No, not all pathogens are killed by freezing temperatures. While freezing can inactivate many bacteria and viruses, some pathogens can survive in a dormant state and may become active again once thawed. Additionally, certain parasites and spores can also withstand freezing. Therefore, freezing is not a guaranteed method for eliminating all harmful microorganisms.

Are all positive temperatures above freezing?
yes
Does freezing kill germs?
Freezing does not kill germs; it simply inactivates them. Many bacteria and viruses can survive freezing temperatures and can become active again once thawed. However, freezing can reduce the number of viable pathogens over time, making it a useful method for food preservation. It's important to note that while freezing slows down microbial growth, it does not eliminate all germs.
How does low temperatures achieve sterilization?
Low temperatures achieve sterilization primarily through the process of freezing, which can inhibit microbial growth and reproduction. At temperatures below freezing, the formation of ice crystals can damage cellular structures and disrupt metabolic processes. While not all microorganisms are killed at low temperatures, the reduced activity and viability significantly lower the risk of contamination. Additionally, certain low-temperature storage methods, like cryopreservation, can preserve biological samples by preventing degradation without necessarily achieving complete sterilization.
What is the cause of the ice in antarctica?
All ice -- everywhere on earth -- results from precipitation combined with freezing temperatures.
What plants are frost sensitive?
Plants like tomatoes, peppers, basil, and beans are all sensitive to frost and can be damaged or killed if exposed to freezing temperatures. It's important to protect these plants by covering them or moving them indoors during cold weather.
Would you find potholes in the roads of regions where temperatures are above freezing all the time Why?
Potholes can still form in regions with temperatures above freezing. When water seeps into cracks in the road and then freezes during the night, it expands, causing the pavement to crack and break. This process repeats and eventually creates potholes, regardless of the region's average temperature.
Does freezing meat make it all right to eat if the animal had a disease?
Freezing meat will kill many types of disease causing organisms, but not all of them. Parasites such as worms will be killed, bacteria will be killed, but viruses can survive freezing. Of course, viruses that infect animals usually will not infect people, they tend to be species specific. So your chances are pretty good.
What is the difference between germs and pathogens?
All germs are pathogens but all pathogens is not germs.
Did any members of the donner party die?
actually almost all of the group died from the lack of food or freezing temperatures
Does the temperature of a tundra biome stay the same all year?
No, the temperature in a tundra biome can vary throughout the year. It generally has long, cold winters with temperatures well below freezing and short, cool summers with temperatures just above freezing.
Does freezing yogurt kill the bacteria present in it?
Freezing yogurt does not kill all the bacteria present in it, but it can reduce the overall number of live bacteria. Some bacteria may survive the freezing process, but the cold temperatures can affect their viability and activity.
What type of desert is dry and can get below freezing temperatures?
All deserts are dry, that is why they are called deserts. All deserts can get below freezing but rarely stay below freezing for more than a few hours. However, cold deserts can get bitterly cold in the winter and stay that way for days.
