Why does the respiratory rate change depending on age?
Because the other Organ systems help with important things, but the respiratory system is the most important because it is basically the breathing system. You need to breath to live, so, the respiratory system is the boss of all the other body systems.(Do not change this, it is the correct answer)
Negative amplitude in waveforms indicates a reversal in the direction of the wave's oscillation. It is significant because it represents a change in the wave's polarity or phase, which can affect how the wave interacts with other waves or systems.
The fact that exercise does not directly impact breathing does not necessarily affect overall physical fitness and performance. Breathing is controlled by the respiratory system, which adapts and improves with regular exercise. While exercise may not directly change breathing patterns, it can improve cardiovascular fitness, muscle strength, and endurance, all of which contribute to overall physical fitness and performance.

yes it is
Breathing on glass is an example of the reversible change because, the air inside the glass can be breathed in again.
if the value of the reactive component was increased, how would it change the waveforms?
in the alveoli
The muscular respiratory and skeletal systems work together to facilitate breathing and support the mechanics of respiration. The skeletal system, particularly the rib cage and spine, provides a framework that protects vital organs and aids in lung expansion. Meanwhile, respiratory muscles, such as the diaphragm and intercostal muscles, contract to change the volume of the thoracic cavity, allowing air to flow in and out of the lungs. This collaboration ensures efficient gas exchange and overall respiratory function.
For air flow: F=(P_alveolar -P_atmosphere)/R When there is no air flow F= 0 and then P_alveolar -P_atmosphere=0, so they equal each other. Hence the Alveolar pressure is equal to that of the atmosphere, between a breathing cycle.
The best way to conduct any scientific experiment is to isolate your variable; you change only one thing, which is your variable, and to the extent that you can, you do not change anything else. If you change more than one thing, then it becomes harder to know which of these changes had whatever experimental result you observe. For example, if you are investigating breathing rate and you change the oxygen content of the air that is being breathed, and you also change the activity level of the subject (let us say, from sitting to walking) and you observe a change in breathing rate, you won't know whether it was in response to the change in oxygen level, the change in activity level, or the change in both. So you just change one thing.
