Q: Process:  - The liver filters blood from the digestive tract - The liver produces bile - The liver produces proteins for blood plasma - The liver converts excess glucose into glycogen for storage - The liver converts ammonia to urea - The liver regulates blood clotting.  Perturbation hypothesis: suppose there is more blood plasma happens, how will it affect the liver having to work HARDER.  Does the supposed perturbation have an effect (direct or indirect) on the process?
A: yes

Q: Process:  - Coal is put in a coal-fired steam station - Water is put in pipes in the coal-fired steam station - The coal is crushed - The coal is moved into a boiler along with hot air - The water is moving through pipes in the boiler - The steam from the water is blown against a turning mechanism - The force of the steam makes the mechanism turn - The mechanism generates electricity.  Perturbation hypothesis: suppose lots more people want coal fires happens, how will it affect There might well be a shortage of fuel.  Does the supposed perturbation have an effect (direct or indirect) on the process?
A: yes

Q: Process:  - You breathe in - Air goes through all the little branches in your lungs to fill up the air sacs, or alveoli - Oxygen goes through the walls of the alveoli and into the capillaries - The oxygen goes into the bloodstream - Oxygen is left and carbon dioxide is picked up - You breathe it out through your lungs -   Perturbation hypothesis: suppose there is less rain happens, how will it affect less oxygen can go into the bloodstream.  Does the supposed perturbation have an effect (direct or indirect) on the process?
A:
no
