[Q]: Process:  - The consumer throws aluminum cans and foil into a recycle bin - The aluminum is collected - Taken to a treatment plant - The aluminum is sorted and cleaned ready for reprocessing - The aluminum is re-melted - Turned into molten aluminum - The aluminum is made into large blocks called ingots - The ingots are sent to mills to be rolled out - The rolled out product is made into new aluminum products.  Perturbation hypothesis: suppose there is more awareness of recycling happens, how will it affect there will be more waste in landfills.  Does the supposed perturbation have an effect (direct or indirect) on the process?
****
[A]: yes


[Q]: Process:  - People separate different materials to be recycled - The recyclable materials go to a recycling center - The recycling center further separates the materials - Large equipment compacts the materials into bales - The recyclable materials are shipped to other recycling centers - The other recycling centers further process the materials that center specializes in - The materials are purchased by manufacturers - The manufacturers process the recycled materials the same way they would use new materials - The recycled materials are incorporated into new products.  Perturbation hypothesis: suppose the air has carbon dioxide happens, how will it affect made into recycled products.  Does the supposed perturbation have an effect (direct or indirect) on the process?
****
[A]: no


[Q]: Process:  - Air is brought in through the mouth - Passes through the lungs - And into the bronchial tissue - The carbon dioxide is removed - The lungs bring the oxygen to the rest of the body.  Perturbation hypothesis: suppose more grapes washed happens, how will it affect a GREATER amount of oxygen being delivered to the blood stream.  Does the supposed perturbation have an effect (direct or indirect) on the process?
****
[A]: no


[Q]: Process:  - One type of air pollution is the addition of carbon dioxide gas into the air - Some scientists believe that releasing too much carbon dioxide into the atmosphere is one of the causes of global warming - This upsets the balance of the carbon cycle - The ozone layer helps protect us from harmful rays from the sun - It is getting damaged from air pollution such as methane gas from livestock and CFCs from spray cans - Acid rain is created when gasses such as sulfur dioxide get high into the atmosphere - The wind can blow these gasses for miles and then they get washed out of the air when it rains - This rain is called acid rain and can damage forests and kill fish.  Perturbation hypothesis: suppose less seeds sprout happens, how will it affect MORE bad effects of pollution.  Does the supposed perturbation have an effect (direct or indirect) on the process?
****
[A]:
no
