Process:  - Food enters the body - Food begins to be processed by the digestive system - The pancreas releases enzymes to aid digestion - Digested food affects the amount of sugar in the blood - The pancreas releases one hormone to lower the blood sugar (glucose) level - The pancreas releases another hormone to raisethe blood sugar (glucose) level.  Perturbation hypothesis: suppose it is the middle of summer happens, how will it affect the pancreas working SOFTER.  Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: no

Process:  - The sun gives off radiation - The radiation is aborbed by the Earth - Some of the radiation goes back into space - Some is trapped by the atmosphere - If too much heat is trapped - Global warming occurs.  Perturbation hypothesis: suppose sun gives off less radiation happens, how will it affect a SMALLER greenhouse effect.  Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: yes

Process:  - You breathe oxygen into your body through the nose or mouth - The oxygen travels to the lungs through the windpipe - The air sacs in the lungs send the oxygen into the blood stream - The carbon dioxide in the blood stream is transferred to the air sacs - The lungs expel through the nose or mouth back into the environment.  Perturbation hypothesis: suppose carbon dioxide can not be transferred to the air sacs 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?
Ans: yes

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 directions are being read wrong happens, how will it affect less carbon atoms rearrange into a new substance.  Does the supposed perturbation have an effect (direct or indirect) on the process?

Ans: no
