2. Consider a cell that has 100 receptors for fibroblast growth factor (FGF). One-fifth of the receptors are each occupied by a molecule of FGF. A) Calculate the entropy of the cell. Assume that the receptors are locked in place (i.e., you are only considering the different ways to distribute the FGF molecules among the receptors). B) Now let's say this cell comes into contact with a cell that has 50 receptors and no bound FGF. Find S as the FGF molecules from the first cell redistribute between the two cells
