(a) calculate the number of cells in a hummingbird assuming the mass of an average cell is ten times the mass of a bacterium. (b) making the same assumption, how many cells are there in a human?

Given :

Average mass of the cell = 10 X mass of bacterium.

Number of cell=  (Mass of humming bird)/ (mass of the [email protected])

a) The mass of a hummingbird is  , while the mass of a cell is  . The number of cells in the hummingbird is

                    〖10〗^(-2)/〖10 X 10〗^(-15) = 〖10〗^12  cells

Number of cells in humming bird = 1012 cells

b) The mass of a person is  .

                    (〖10〗^2  kg)/(10 X 〖10〗^(-15) )= 〖10〗^16  cells

Number of cells in human = 1016 cells
