The term sterilize refers to the use of which types of procedures to destroy all microbial life?

The term sterilize is defined as the process of eliminating all forms of microbial life, including bacteria, viruses, fungi, and spores. This can be achieved through various methods that either physically or chemically alter the environment to ensure complete destruction of all microorganisms.

Physical procedures for sterilization often include methods such as autoclaving (using pressurized steam), dry heat sterilization, or irradiation. These techniques physically disrupt the cellular structures of microorganisms. On the other hand, chemical procedures involve the use of disinfectants and sterilants, such as ethylene oxide or hydrogen peroxide, that can effectively kill all microbial life by altering their biochemical structures.

The other types of procedures mentioned in the options focus either on specific aspects of sterilization or do not cover the full range needed for comprehensive microbial destruction. Therefore, the combination of both physical and chemical approaches is essential for achieving true sterility, making this choice the most accurate representation of the broad methods available to achieve sterilization.
