Question

question 3 which agar plate resulted from the student not sterilizing their wire loop between streaking each sector?

Explanation:

In the streak plate method, sterilizing the wire loop between sectors dilutes the bacteria, leading to fewer colonies in subsequent sectors (like sector 3 having isolated colonies when done correctly). If the loop isn't sterilized, bacteria aren't diluted, so all sectors (1, 2, 3) will have dense, overlapping colonies without proper dilution. The left agar plate shows dense growth in all sectors (no dilution from non - sterilized loop), while the right has diluted growth in sector 3 (loop was sterilized). So the left plate (with dense growth in all sectors) is the result of not sterilizing the loop.

Answer:

The left agar plate (the one with dense bacterial growth in all three sectors: 1, 2, and 3)
