When a class is through using a culture, it should be deposited on the cleanup cart rather than being poured down the sink drain because doing so runs the danger of contaminating and blocking the sink and necessitating proper disposal of the contamination, which could contaminate the water supply.
<h3>Which of the following actions is necessary if a microbial culture is spilled?</h3>
After telling the instructor that you spilled or dropped a culture, you should wipe the area down with a paper towel and use disinfectant. Clean up the mess with new paper towels after waiting fifteen minutes. After using the restroom, don't forget to wash your hands completely and dispose of the paper towels. Take the proper steps to dispose of any shattered glass.
<h3>Why did you need to use ethanol to clean the work area?</h3>
To maintain an aseptic/sterile environment, 70% ethanol is frequently used to clean surfaces that have been contaminated with microorganisms. Because 70% ethanol will negatively impact bacteria's cell walls and their ability to grow and multiply. Osmotic pressure will be produced when ethanol and water are combined, which is another factor.

Since a greater percentage of students who took the morning test failed the test than students who took the afternoon test, more of Orloff’s morning history students than afternoon history students will have to take the retest. The conclusion above is not necessarily valid because more student may have taken the test in the afternoon than in the morning.
