Answer :
The number of cells in a hummingbird, given the data is 10¹² cells
How to determine the mass of one cell
We'll begin by obtained the mass of a cell. This can be obtained as illustrated below:
Mass of 1 cell = 10 × mass of bacterium
But
Mass of bacterium = 10⁻¹⁵ Kg
Thus,
Mass of 1 cell = 10 × 10⁻¹⁵ Kg
Mass of 1 cell = 10⁻¹⁴ Kg
How to determine the number of cells in the hummingbird
The number of cells in the hummingbird can be obtain as follow:
- Mass of 1 cell = 10⁻¹⁴ Kg
- Mass of hummingbird = 10⁻² Kg
- Number of cells =?
Number of cells = Mass of hummingbird / mass of 1 cell
Number of cells = 10⁻² / 10⁻¹⁴
Number of cells = 10¹² cells
Thus, the number of cells in the hummingbird is 10¹² cells
