The development of an adult organism from a zygote isn’’t quite that simple. In addition, things can go awry with cell division – notably the transformation of normal cells into cancer cells that divide in an uncontrolled way. If a single cancer cell in a tissue of the human body divides once every day, how long will it take for that cell to produce a tumor 30 cm3in volume? Assume that the original cell has a volume of 10-9cm3, and determine the integral number of divisions that gives the closest result.
