Calculate the number of cells in a hummingbird, assuming it has a mass of 10-2 kg.
Nikitich [7]

The number of cells in a hummingbird, given the data is 10¹² cells

<h3>How to determine the mass of one cell</h3>

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

<h3>How to determine the number of cells in the hummingbird</h3>

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

What is an example of a non-chemical<br> water pollutant?
hjlf

Answer:

Water pollution is the contamination of water bodies, usually as a result of human activities. Water bodies include for example lakes, rivers, oceans, aquifers and groundwater. Water pollution results when contaminants are introduced into the natural environment. For example, releasing inadequately treated wastewater into natural water bodies can lead to degradation of aquatic ecosystems. In turn, this can lead to public health problems for people living downstream. They may use the same polluted river water for drinking or bathing or irrigation. Water pollution is the leading worldwide cause of death and disease, e.g. due to water-borne diseases.
