Process:  - Bats fly through an area - The bat makes sounds with their mouth or nose - The sound waves travel away from the bat - The sound waves hit objects - The sound waves bounce off the objects back towards the bat - The bat hears the sound waves echoing off the objects - The bat knows where the objects are because of where the sound echoed from - The bat doesn't hurt itself by hitting the objects.  Perturbation hypothesis: suppose there will be more minerals dissolved happens, how will it affect STRONGER echolocation.  Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: no

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 the persons mouth is taped shut happens, how will it affect more warm air from outside pushes into low pressure area.  Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: no

Process:  - A bird picks a spot high spot, often in a tree - The bird collects bits of sticks and grass - The sticks and grasses are placed between support branches - Leaves, mud and spider webs are added to the sticks - The mud, leaves and webs glue the sticks together - The solid nest supports the eggs -   Perturbation hypothesis: suppose more ecological damage from humans happens, how will it affect the sticks are less glued together.  Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: yes

Process:  - A fuel is heated in an oven - Above the oven is a tank of water that is sealed - The tank of water begins to boil above the oven - A the water boils steam is created - The steam is denser than air so it needs a place to go - The steam is forced out of the tank and into a piston - The piston moves up - The valve of the piston closes - The valve on the next piston opens - The steam fills the next piston, driving it up, and the other one down -   Perturbation hypothesis: suppose there is more moisture in the air happens, how will it affect more water vailable.  Does the supposed perturbation have an effect (direct or indirect) on the process?

Ans: no
