Of course, 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 13 cm3 in volume? assume that the original cell has a volume of 10-9 cm3, and determine the integral number of divisions that gives the closest result.
