Notes sound fiber asians deflect the hair cells its like flattening the fibers of a carpet. That generates an electrical signal which is sent to the brain and we perceive a sound. Then stand up again and all ready for the next sound. The different pitches are registered in different parts of the cockpit. I know its are detected by the hairs at the bottom. Lower ones further up. And the lowest notes at the very top. Enabling us to hear a wide range of pitches. And their cells are very sensitive if theyre exposed to too much stress or for too long they can be damaged and move on the real sounds
And you are welcome to the program in Europe Africa is being hits hard by Climate Change but the worst could be yet to come if action is not taking the world much or a logical the continent was impacted by your number of extreme weather events in 2019 including cycle and you die one of the worst tropical storms on record. Also suffer droughts rising temperatures. Its just one of the main drivers on the continent devastation and the number of recommendations to try to read the worst.
