Problem: Process:  - Bread is exposed to the elements - Bread absorbs water from the air - Bread absorbs warmth from the air - Dust particles with mold spores fall on bread - Mold spores start to consume the bread for energy - Mold colonies grow until they are visible.  Perturbation hypothesis: suppose the bread is cleaned off happens, how will it affect an increase in dust particles on the bread.  Does the supposed perturbation have an effect (direct or indirect) on the process?

A: yes


Problem: Process:  - A person eats food - The person's blood sugar level rises - The pancreas receives a signal to release insulin - Insulin is released into the bloodstream - Insulin signals cells to absorb sugar - The cells absorb sugar from the bloodstream - The cells use the sugar as energy.  Perturbation hypothesis: suppose having genetic illness happens, how will it affect LESS use of insulin in the body.  Does the supposed perturbation have an effect (direct or indirect) on the process?

A: yes


Problem: Process:  - Warm water floats up from the ocean - A pocket of low pressure air is created near the surface of the ocean - Warm air from outside areas pushes into the low pressure area - The warm air keeps rising and forms clouds - The wind is getting fed moisture that evaporates from the ocean - This moisture causes the swirling air and clouds to grow bigger - As it gets bigger the wind rotates faster.  Perturbation hypothesis: suppose more sunny days happens, how will it affect LESS POWERFUL hurricanes.  Does the supposed perturbation have an effect (direct or indirect) on the process?

A: no


Problem: Process:  - The bird picks a tree - The bird collects twigs and other refuse - The bird makes a flat base with twigs - The bird makes sides with twigs and other things - The bird adds softer material to the inside - The nest is done.  Perturbation hypothesis: suppose there are fewer trees happens, how will it affect there will be more trees.  Does the supposed perturbation have an effect (direct or indirect) on the process?

A:
yes
