d) swearing gloves when handling sterile laboratory equipment
e) using a Bunsen burner (flame) to heat a wire inoculating loop prior to use

Answer 1

To maintain an aseptic work environment in a laboratory, it is important to take steps to prevent contamination and to sterilize equipment and tools. Using a Bunsen burner flame to heat an inoculating loop is one way to sterilize the loop before use.

Step-by-step explanation:

When working with sterile solutions in a laboratory, it is important to take precautions to prevent contaminants from entering. This can include using sterilized equipment, such as pipettes and glassware, and sterilizing metal tools like inoculating loops before use. One method of sterilizing the inoculating loop is by using a Bunsen burner flame to heat the wire, which kills any microbes present.
