Question: 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.  Perturbation hypothesis: suppose less stormy weather happens, how will it affect less seeds grow.  Does the supposed perturbation have an effect (direct or indirect) on the process?
Answer: no

Question: Process:  - Carbon dioxide enters the leaves through the stomates by diffusion - Water is transported to the leaves in the xylem - Energy harvested through light reaction is stored by forming ATP - Carbon dioxide and energy from ATP are used to create sugar - Oxygen exits the leaves through the stomata by diffusion - The plant reuses the water or the water exits through the stomata as water vapor.  Perturbation hypothesis: suppose less oxygen exits through leaves happens, how will it affect LESS sugar and oxygen being produced.  Does the supposed perturbation have an effect (direct or indirect) on the process?
Answer: yes

Question: 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 less insulin happens, how will it affect the pancreas working HARDER.  Does the supposed perturbation have an effect (direct or indirect) on the process?
Answer:
no
