While extreme high or low temperatures technically do not kill viruses, the influenza virus and many others are deactivated at temperatures ranging from 165 to 212 degrees Fahrenheit, the boiling point for water. Since viruses lack many of the basic structures and functions necessary to be considered a living organism, they technically cannot die.Know More
Since most viruses are deactivated at temperatures between 165 and 212 degrees Fahrenheit, food scientists advise to heat up meat to at least 165 degrees before serving. These temperatures kill bacteria, as well.
Viruses can withstand freezing temperatures, however. There are known HIV infection cases in which contaminated frozen human material has been implanted into a recipient and infected the patient.Learn more about Biology
Biological mutant agents are substances that change the genetic material of organisms, such as DNA, and include certain chemicals and rays, such as ultraviolet radiation, X-rays and gamma rays, along with viruses and bacteria. Many mutagenic agents cause cancer, and are dually classified as carcinogens. While mutant agents cause artificial changes in genetic codes and replication, some mutations occur naturally and are caused by spontaneous hydrolysis and errors in DNA replication, recombination and repair.Full Answer >
During their life span, most viruses are both living and non-living organisms. Whether they are living or non-living depends on if they have found a host.Full Answer >
By maintaining homeostasis, organisms remain healthy, strong and stable, with protection from the attacks of foreign organisms, such as viruses, bacteria and fungi. Homeostasis enables organisms to remain balanced while living in constantly changing environments.Full Answer >
Freezing food or other items does not kill all the bacteria or other microorganisms present. Freezing temperatures may kill some bacteria, and the cold prevents bacteria from growing and multiplying as long as the temperature remains below freezing; however, bringing the food back to room temperature allows the bacteria to wake up and begin multiplying once more.Full Answer >
