Please answer this: Process:  - You place aluminum cans and other products into recycling bins - Your town or a private company collect and transport the aluminum to a recycling facility - The aluminum is sorted and cleaned at the central recycling facility - The aluminum is melted down to remove coatings and inks - The melted aluminum is formed into large formations called ingots - The ingots are transported to another facility and rolled out to make them easier to manipulate - The ingots can now be turned into new aluminum products.  Perturbation hypothesis: suppose more aluminum sorted happens, how will it affect LESS aluminum cans being recycled.  Does the supposed perturbation have an effect (direct or indirect) on the process?

Please answer this: Process:  - People breathe and expel carbon dioxide - Engines produce carbon dioxide - Living things produce waste - Waste decomposes - Decomposition produces methane - Water evaporates - Water vapor joins the atmosphere - Carbon dioxide, water vapor and methane are greenhouse gases -   Perturbation hypothesis: suppose an increase in fuel prices happens, how will it affect LESS greenhouse gases.  Does the supposed perturbation have an effect (direct or indirect) on the process?

Answer: yes


Please answer this: Process:  - Food is put into mouth - Food is chewed and mixed with saliva (spit) - Food travels down the esophagus (throat) - Food travels into the stomach - Acid in the stomach breaks the food down further - Food travels into the small intestine - Nutrients from food are absorbed into the blood stream - Food travels into the large intestine - Most of the remaining material is now waste - The waste is eventually removed from the body.  Perturbation hypothesis: suppose more food is put into the mouth happens, how will it affect LESS food being digested.  Does the supposed perturbation have an effect (direct or indirect) on the process?
