Problem: Process: - Water comes into contact with something made of iron - The water combines with carbon dioxide in the air to form carbonic acid - As the acid is formed, the iron starts to dissolve - Some of the water breaks down into hydrogen and oxygen - The free oxygen and dissolved iron bond together - They form iron oxide, which is rust - suppose carbonic acid does not form happens, how will it affect iron oxide will form. Which of the following is the supposed perturbation? - directly impacting a step of the process - indirectly impacting a step of the process - not impacting any step of the process

A: indirectly impacting a step of the process

Problem: Process: - A forest fire starts - The trees and plants burn - The animals lose their homes - If the animals can not escape, they may die from smoke inhalation - The plants that provide food are gone - The animals have little to eat - suppose more forest rangers employed to monitor human activities happens, how will it affect a GREATER negative effect on animals. Which of the following is the supposed perturbation? - directly impacting a step of the process - indirectly impacting a step of the process - not impacting any step of the process

A: indirectly impacting a step of the process

Problem: Process: - Get some seeds - Pick a spot to plant them - Dig a hole in the dirt - Put the seed in the hole - Pour some water on the seed and hole - Cover up the hole - Press down on it - Spray some plant food on it. suppose using old seeds happens, how will it affect LESS vegetables. Which of the following is the supposed perturbation? - directly impacting a step of the process - indirectly impacting a step of the process - not impacting any step of the process

A: indirectly impacting a step of the process

Problem: Process: - Human industry produces chemical compounds - Chemical compounds rise into the air - Chemical compounds mix with elements in clouds - The affected rain falls to the earth - The affected rain can harm natural and man-made objects because of its acidic content. suppose more carbon dioxide enters the leaf happens, how will it affect MORE damage by acid rain. Which of the following is the supposed perturbation? - directly impacting a step of the process - indirectly impacting a step of the process - not impacting any step of the process

A:
not impacting any step of the process
