What does sterilization kill?

  1. Most bacteria

  2. Visible dirt

  3. All microbial life

  4. HIV, Tuberculosis, and Hepatitis

The correct answer is: All microbial life

Sterilization is a process that destroys or eliminates all forms of microbial life, including bacteria, viruses, fungi, and spores. This means that options A, B, and D are incorrect. While option A is partially correct in that sterilization does kill most bacteria, it also eliminates other forms of microbial life. Option B is incorrect because visible dirt does not necessarily carry harmful microbes. Option D is incorrect because sterilization methods are effective against a wide range of microorganisms, including HIV, tuberculosis, and hepatitis. However, sterilization does not just target these specific microorganisms.
