Red Seal Cosmetology Practice Exam

What does disinfection aim to achieve in a chemical process?

1. To destroy all organisms

2. To clean surfaces only

3. To destroy most harmful organisms, but not necessarily all

4. To perfume the environment

The correct answer is: To destroy most harmful organisms, but not necessarily all

Disinfection aims to kill most microorganisms, but it does not necessarily destroy all of them. Option A is incorrect because complete destruction of all organisms is the goal of sterilization, not disinfection. Option B is incorrect because disinfection is not limited to cleaning surfaces, it can also involve the treatment of water or air. Option D is incorrect because adding perfume to the environment is not a main objective of disinfection. Therefore, option C is the best answer as it accurately describes the overall goal of disinfection in a chemical process.
