Part A An average adult human can be modeled as a 70 kg, 140-cm-tall cylinder with a diameter of 25 cm. Use the approximate mass of a mammalian cell of 10 2 kg to make an order-of-magnitude estimate, to one significant figure, of the number of cells in a human body by considering a person's mass. Express your answer to one significant figure.
