Question 4 • Biology

Which action is an aseptic technique that would reduce the chance of bacteria on a lab table contaminating a lab notebook?

Answer
A
covering the surface of the lab table with paper towels
B
wiping off the surface of the lab table with a disinfectant
C
wearing protective gloves when touching the lab table
D
tying back long, loose hair before writing in the lab notebook

Explanation

Disinfectant kills or reduces bacteria on the lab table, lowering the chance that bacteria will transfer from the surface to the notebook. Therefore, wiping the table with disinfectant is the aseptic technique. Paper towels may cover the surface but do not necessarily remove or kill bacteria.
