Its is polar, meaning it has a positive and negetive end
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:
The ocean produces oxygen through the plants (phytoplankton, kelp, and algal plankton) that live in it. These plants produce oxygen as a byproduct of photosynthesis, a process which converts carbon dioxide and sunlight into sugars the organism can use for energy.

The answer which is not a characteristic of fungi is that B. their cell walls consist mainly of cellulose.
As a matter of fact, the cell walls of plants consist mainly of cellulose, whereas the fungi cell walls consist of chitin.
Answer:
Traits acquired during an organism's lifetime cannot be passed
Explanation:
<em>The law of use and disuse of organs as postulated by Jean Lamarck was wrong due to the fact that environmentally acquired characters cannot be passed to offspring.</em>
Changes to organisms that are not the level of the gene cannot be passed to the offspring. <u>For example, a wrestler that got big muscles due to constant work out cannot pass big muscles to his offspring. The offspring will need to work out in order to have big muscles. This is because big muscles in the wrestler is environmentally acquired.</u>
Only changes that happen to the genome of an organism (mutation) can be passed to offspring.
