Based on these results the importance of soap and time they are very important because using soap guarantees clean hands and washing your hands for a good amount of time will also ensure that your hands have been completely clean.

6.Analyze the graphs. What do they indicate about the time it may take to effectively wash your hands? I would say in order to ensure your hands are clean I would recommend to wash your hands a for a good 20 seconds.
7.Describe the various defense mechanisms your body has to fight pathogens, nonspecific and specific. How does not washing your hands properly affect these mechanisms? Some of the various defense mechanisms our bodies have are - Saliva, mucus, tears, skin, inflammatory response, white blood cells, fever, and the immune system. Not washing your hands can affect these mechanisms by making it so that if you were to touch something dirty with your hands these mechanisms can fight them off.
