(PLEASE HELP ASAP) (WILL GIVE BRAINLIEST AND THANKS) As an airplane rises through the atmosphere, machines cause the pressure in
side the cabin to decrease. As the airplane descends toward Earth, machines cause the pressure inside the cabin to increase. Based on your observations from the Can Crush Lab, explain why these changes in pressure are necessary.
Well, from what I know.. In high elevations, there are fewer air molecules above a given surface than a similar surface at lower levels. Most of the atmospheres molecules are held close to the earth's surface by the force of gravity and hence air pressure decreases rapidly at first, then more slowly at higher levels. Sooooo if the pressure in an airplane cabin isn't changed, it can cause injury or harm to passengers and oxygen equipment is required above 8,000 altitude.
The answer is Genetic Tolerance because the definition of it is "Genetic resistance (or genetic tolerance) refers to the ability of certain organisms to endure environmental conditions that are extremely stressful or lethal to non-adapted individuals of the same species ."
