Разъяснение: The method that does not destroy the hepatitis virus is sterilizing. Sterilization is a process that involves killing all microorganisms including viruses, bacteria, and fungi. This is usually done by high temperatures or chemicals. The other options, such as freezing, boiling, washing, and drying can effectively eliminate or inactivate the hepatitis virus. Freezing can slow down or stop the growth of the virus, boiling can kill it by denaturing its proteins, washing can physically remove the virus from surfaces, and drying can lead to the desiccation and death of the virus.
Дополнительный материал: Which of the following methods would be ineffective in destroying the hepatitis virus? a. freezing b. sterilizing c. boiling d. washing e. drying?
Совет: To understand the effectiveness of different methods in destroying a virus, it is important to learn about their mechanisms of action. For example, studying the effect of temperature on virus stability, the denaturation of proteins, and the physical removal of viruses through cleaning can provide insights into how different methods work.
