Process:  - Plants and animals long ago died - They are buried under layers of soil - Pressure builds over time - The remains liquefy - The carbon atoms rearrange to become a new substance.  Perturbation hypothesis: suppose the area is disturbed by an earthquake slowing the development of pressure happens, how will it affect MORE oil.  Does the supposed perturbation have an effect (direct or indirect) on the process?

Answer: yes


Process:  - Cells obtain glucose and oxygen - The glucose and oxygen create carbon dioxide - The cells release energy - The cells don't have enough oxygen to repeat this - The cells obtain more oxygen from the air - The cells repeat this process.  Perturbation hypothesis: suppose owls fly out less happens, how will it affect LESS oxygen reaching the body.  Does the supposed perturbation have an effect (direct or indirect) on the process?

Answer: no


Process:  - Food is taken into the mouth - The food is chewed - Saliva mixes with the food and starts breaking it down - The chewed food travels down the esophagus to the stomach - The stomach secretes acid - Grinds and mixes the food - The food moves to the small intestine - The small intestine uses enzymes to further break down the food - The food passes into the colon - The food is expelled from the body.  Perturbation hypothesis: suppose Less food is eaten happens, how will it affect the digestion process will increase.  Does the supposed perturbation have an effect (direct or indirect) on the process?
