The pressure inside your lungs and the pressure outside them fluctuate as you breathe. An illustration of a pressure gradient is this.
<h3>What is an example of pressure gradient?</h3>
- The pressure gradient is the amount by which the atmospheric pressure drops in a location at a particular time.
- A pressure gradient is demonstrated by gale-force winds in one city changing to a moderate breeze after an hour. the rate of the pressure in space decreasing (gradient) at a specific period.
<h3>How does pulmonary ventilation change with pressure gradient?</h3>
Thoracic ventilation Because air moves down a pressure gradient, or from an area of greater pressure to an area of lower pressure, the difference in pressures is what drives pulmonary ventilation.
When breathing in and out, the respiratory airways restrict the flow of air. The air must be transported by the pressure gradient from the mount (or nose) to the pulmonary alveoli.

Answer:
=)
Explanation:
A cell is very much like a city and one example is like how cytoplasms are like factories because they break down and absorb energy and they hold the organelle
the answer is the photosynthesis!
Answer:
C. Lizards were the first organisms on Earth to have limbs.
Explanation:
This cladogram illustrates when and in what species novel anatomical traits occurred. All the organisms that follow after a certain point will have this trait present. Thus, earthworms are the first species to evolve segmented bodies which will be present in all the following organisms such as salmons. Here, segmentation is found in the vertebrae of the backbone as well as in the muscles and nerves that spread from the spinal cord, at a finer level.
This cladogram does not illustrate the evolutionary time relationship between different species. Thus, it cannot be inferred that the kangaroos evolved after earthworms.
