- Attached below is the study about the effects of handwashing and the effectiveness of soap against bacteria. What conclusions can be generated from this result? (see rubrics for the point marking) A before washing hands C 10 second hand wash B D hot water only rinse 30 second hand wash Figure 8: Agar plates with bacteria A) before washing hands B) after rinsing hands in hot water C) After washing hands with soap for 10 seconds and D) after washing hands for 30 seconds.
