Use of chemical agents to destroy microbes on skin or tissues Reinoval of microbes from surfaces by scrubbing Removal or destruction of all microbes Use of chemical agents to destroy microbes on surfaces used by the public Use of physical/chemical agents to destroy microbes on non-living objects Free of contamination by pathogens Antisepsis (antiseptic) Aseptic Degerming Sanitization Sterilization Disinfection

List the microbial targets of disinfecting chemicals, how that affects the microbe, and provide one example of a chemical agent that affects that structure.

Which of the following are true regarding UV disinfection? Mark all that apply. Water must be clear, so light can kill pathogens It is the cheapest method of disinfection The water has to flow at a specific speed past the UV light Only about 85% of pathogens are killed by UV It is very rarely used in water disinfection due to high costs

how is UV radiation a good type of control mechanism against microbial growth?please expalin what happens to the microbe and affects this control cause.
