Answer:
[tex]10^{12}\ cells[/tex]
[tex]10^{16}\ cells[/tex]
Explanation:
Mass of cell = [tex]10\times 10^{-15}=10^{-14}\ kg[/tex]
Mass of hummingbird = [tex]10^{-2}\ kg[/tex]
Mass of human = [tex]10^{2}\ kg[/tex]
Number of cells is given by
[tex]n=\dfrac{\text{Mass of hummingbird}}{\text{Mass of cell}}\\\Rightarrow n=\dfrac{10^{-2}}{10^{-14}}\\\Rightarrow n=10^{12}\ cells[/tex]
The number of cells in a hummingbird is [tex]10^{12}\ cells[/tex]
[tex]n=\dfrac{\text{Mass of human}}{\text{Mass of cell}}\\\Rightarrow n=\dfrac{10^{2}}{10^{-14}}\\\Rightarrow n=10^{16}\ cells[/tex]
The number of cells in a human is [tex]10^{16}\ cells[/tex]
