Lakesha was culturing bacteria She used aseptic technique to make sure there was no contamination. When she was finished, she used water to clean the surface of her table. She then put the sample in the incubator, removed her gloves, and washed her hands with soap and water Which error did Lakesha make in her process? A student should not culture bacteria in the lab Aseptic technique is used for chemical spills She does not need to wash her hands after culturing bacteria She should be using a disinfectant on her table not just water

## Step 1The problem is about the aseptic technique, which is a set of practices that prevent contamination of cultures in a laboratory. Lakesha, the student, is performing an experiment involving bacteria culture. She uses aseptic techniques to ensure no contamination, cleans the table with water, puts the sample in the incubator, removes her gloves, and washes her hands with soap and water.## Step 2The question asks us to identify any errors in her process. The options provided are:A. A student should not culture bacteria in the labB. Aseptic technique is used for chemical spillsC. She does not need to wash her hands after culturing bacteriaD. She should be using a disinfectant on her table not just water## Step 3Option A is incorrect because students can culture bacteria in the lab, provided they follow the correct procedures.## Step 4Option B is also incorrect because aseptic techniques are not just for chemical spills but also for biological experiments.## Step 5Option C is incorrect because it is important to wash hands after handling bacteria to prevent the spread of bacteria.## Step 6Option D is the correct answer. While it is important to clean the table after an experiment, using a disinfectant is more effective than just using water. Disinfectants are designed to kill bacteria and other microorganisms, ensuring that the table is completely free of any potential contaminants.
