Problem: Process:  - Get the ice tray - Remove any ice cubes currently in the tray - Fill the tray with cold water - Ensure the tray is evenly filled to an appropriate level - Open the freezer - Place the tray in the freezer - Close the freezer door - Wait.  Perturbation hypothesis: suppose there is more limestone happens, how will it affect at most 20 C degrees.  Does the supposed perturbation have an effect (direct or indirect) on the process?

A: no


Problem: Process:  - An animal eats a lot of food to fatten up - The animal finds or builds a suitable place to hibernate where they can stay warm and protected - The animal moves into their den - Their heart rate and breathing slow down to conserve energy - They emerge from the den when the weather is warming up again.  Perturbation hypothesis: suppose the animal does not fatten up happens, how will it affect HELPING the animal to hibernate properly.  Does the supposed perturbation have an effect (direct or indirect) on the process?

A: yes


Problem: Process:  - Salt water is contained in a factory or plant - The water is boiled to a very high tempature - The salt becomes seperated from the water - The salt is removed - The water is able to be drank at this point.  Perturbation hypothesis: suppose the heat source gets very hot happens, how will it affect the salt separates from the water.  Does the supposed perturbation have an effect (direct or indirect) on the process?

A: yes


Problem: Process:  - A mold spore floats through the air - The spore lands on a piece of bread - The spore grows hyphae into the bread - The mold forms a colony - Sporangiophores grow upward - The mold sends out spores.  Perturbation hypothesis: suppose more Sporangiophores grow upward happens, how will it affect LESS mold forming on bread.  Does the supposed perturbation have an effect (direct or indirect) on the process?

A:
