Process:  - Iron is exposed to oxygen - Is exposed to air - A chemical reaction occurs - The iron starts to oxidize - The iron starts to rust.  Perturbation hypothesis: suppose more eggs produced happens, how will it affect LESS rust forming.  Does the supposed perturbation have an effect (direct or indirect) on the process?

Answer: no


Q: Process:  - Sunlight passes through the glass into the greenhouse - The plants and floor absorb the the sunlight - The absorbed sunlight is converted to heat - The heat cannot escape the glass - The heat is trapped in the greenhouse - The hot air rises - The colder air at the top is pushed to the bottom - The colder air is then warmed by the floor and the plants.  Perturbation hypothesis: suppose more heat is tracked happens, how will it affect the greenhouse being HOTTER.  Does the supposed perturbation have an effect (direct or indirect) on the process?
A: yes


Question: Process:  - Bats and other animals produce a high-pitched tone - The sound travels in waves, as sound does - The sound "bounces" off of a nearby object - The sound wave returns to the bat - The bat hears the echoed sound - Folds in the bat's ear and adaptations in the bat's brain enable it to determine the size, shape, and position of the other object via the properties of the returned sound waves - Other animals use echolocation in generally similar ways -   Perturbation hypothesis: suppose less body temperature occurs happens, how will it affect STRONGER echolocation.  Does the supposed perturbation have an effect (direct or indirect) on the process?
Answer: no


[Q]: Process:  - Water from the ocean washes onto beaches in waves - The waves contain sediment from the ocean - The water and particles in it hit rocks and sand on the beach - The wind and current sometimes push the water and particles harder - Tiny parts of the rocks on the shore come off the larger rocks - The waves pick up sand and small rocks from the beach - The waves go back out into the ocean - The waves carry the new particles with them - Rocks and the beach look a little different.  Perturbation hypothesis: suppose when the wind decreases happens, how will it affect LESS erosion by the ocean.  Does the supposed perturbation have an effect (direct or indirect) on the process?
****
[A]: yes


input: Please answer the following: Process:  - Muscles work by expanding and contracting - A muscle fiber gets a signal from its nerve - Proteins and chemicals release energy to either contract the muscle or relax it - When the muscles contracts the bones connected to he muscle are pulled closer together - When the muscle relaxes the bones move farther apart.  Perturbation hypothesis: suppose The muscle fibers receive more nerve signals happens, how will it affect muscles contracting LESS INTENSELY.  Does the supposed perturbation have an effect (direct or indirect) on the process?
++++++++++
output: yes


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 the bigger aircraft failed a safety check happens, how will it affect water freezes less often.  Does the supposed perturbation have an effect (direct or indirect) on the process?
