Process:  - Water gets into cracks in rocks - The water freezes into ice - The cracks expand - Over time the rocks split - The rocks are now in smaller pieces.  Perturbation hypothesis: suppose more aluminum is re-melted happens, how will it affect cracks expand less.  Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: no

Process:  - Bacteria enters the body - Bloodstream - Cells in the body are attacked - Cells are killed - Different kinds of sickness are formed.  Perturbation hypothesis: suppose antibiotics are given quickly happens, how will it affect cells in the body are not attacked.  Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: yes

Process:  - Magma cools inside the crust - Magma crystalizes - Lava cools on the surface - Lava crystalizes - Minerals dissolved in water crystlize.  Perturbation hypothesis: suppose lava is turned onto crystals happens, how will it affect water breaks down crystals.  Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: yes

Process:  - The kidneys receive blood from the renal artery - They process it with millions of tiny nephrons - Remove all the waste - The kidneys return the blood back to the body through the renal artery - Send the urine with the waste to the bladder through the ureters.  Perturbation hypothesis: suppose Kidneys produce urine after filtering the blood happens, how will it affect the kidney is not functioning properly.  Does the supposed perturbation have an effect (direct or indirect) on the process?
