1. All the cells in a culture need to be moving for the culture to be described as motile? Why or why not?

2. Unstained cells have very little contrast. What single adjustment could you make to your microscope that would make the cells easier to see while at the same time reducing evaporation of your sample?

3. How did you differentiate true motility from Brownian motion and water currents?

4. Imagine that you've prepared a hanging drop slide but were called out of the room for an hour before being able to look at it. When you return, examination of the slide shows motility. Would you be satisfied with this result? What if the slide showed no motility when you returned?

Help me with these questions please, thank you so much!
