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

Dertemine the maximum volume of the air breathed in during the period of rest for each minute
pshichka [43]

The maximum volume of air breathed in during the period of rest for each minute is 500 ml also known as tidal volume.

Tidal volume is simply each breath a person takes. It is a significant factor in both minute and alveolar ventilation. The quantity of air that enters the lungs each minute is measured by minute ventilation also referred to as total ventilation. It is a function of both tidal volume and respiratory rate.

A physiological term called tidal volume (Vt or TV) is used to indicate how much air is generally moved during inspiration and expiration when you are at rest. Spirometry, a non-invasive test, is used to measure it. Adults breathe on average seven milliliters (mL) every kilogram (kg) of ideal body weight.

When it comes to configuring the ventilator in critically ill patients, tidal volume is crucial. Delivering a tidal volume that is both large enough to sustain proper breathing and small enough to prevent lung trauma is the objective.
