Question

What is the purpose of the mechanical process called scrubbing?

1) To remove all visible dirt and debris
2) To remove many disease-causing germs
3) To clean using soap and water or detergent and water
4) All of the above

Answer 1

Scrubbing serves to remove visible dirt, eliminate many germs, and involves cleaning with soap and water, which makes it appropriate for all of the listed purposes.

Step-by-step explanation:

The purpose of the mechanical process called scrubbing is essentially all of the above: to remove all visible dirt and debris, to remove many disease-causing germs, and to clean using soap and water or detergent and water. Scrubbing involves gently to firmly rubbing a surface or skin with a mild chemical, like soap, to significantly reduce microbial numbers, thus helping to avoid the transmission of pathogenic microbes. Soap, being an excellent surfactant, destroys microorganisms by damaging their cellular membranes and denaturing their proteins. Furthermore, it helps in emulsifying oils so they can be washed away with water. In clinical settings like hospitals, scrubbing extends beyond standard handwashing to reduce the normal microbiota to prevent microbial introduction into surgical wounds.

The purpose of the mechanical process called scrubbing is to clean using soap and water or detergent and water. Scrubbing helps to remove all visible dirt and debris, as well as many disease-causing germs. It is an effective way to reduce the microbial load on surfaces or tissues by gently scrubbing with mild chemicals.
