r^2=6Dt , where D is the diffusion coefficient of thediffusing object and t is the time that the object is allowed to diffuse. If the diffusion coefficient, D, of a small protein is 5 x 10^-10 m2 s-1, how long (on average) does ittake for the protein to diffuse across a parasitic wasp that is 189 um long ?
I asked earlier a question, and I got this answer. Now, my question is: how do you get the 2.5cm= 100um? I have taken a picture of the paramecium in question, with the scale bar (100um), and a ruler showing it’s measurement is around 2.5cm. Is that how we got the 2.5?

Consider a batch culture of sphere-shaped bacteria in a growth medium or broth, in which the mean cell diameter of the bacteria is 2.0 μm (micron). Show all your calculations and assumptions in answering the questions below: What is the volume of one of these sphere-shaped cells, expressed in liters? If there are 3 x 10^12 cells in one liter of this culture broth, what percentage of the volume is occupied by bacteria and what percentage is occupied by the cell culture broth (water only)? If the cells contain 80% water, what is the dry cell concentration, expressed as “grams dry weight/Liter of broth”? You should assume that the density of the cells dry mass is approximately 1.0 gr/cm3
