Q: Process:  - A photovoltaic cell is created with two layers of semiconductor material - The top layer are &#x27;doped&#x27; with impurities to allow a negative charge - The bottom layer are &#x27;doped&#x27; to allow for a positive charge - This produces an electric field that allows electrons to flow from negative to positve - Sunlight enters the cell - Energy from sunlight knocks electrons loose in both fields - This prevents the flow of electrons from negative to positive - Adding an external circuit allows the exchange to continue - Give the cells owner a flow of electricity.  Perturbation hypothesis: suppose the dishwasher isn't working happens, how will it affect LESS solar power being generated.  Does the supposed perturbation have an effect (direct or indirect) on the process?
A: no

Q: Process:  - Forest fires burn forests - The animals living in the forest have fewer places to hide - Predators can now find their prey eaiser - Birds will fly away from the area - Waters warm up which hurts the fish swimming in them.  Perturbation hypothesis: suppose more birds would leave the area happens, how will it affect a GREATER negative effect on animals.  Does the supposed perturbation have an effect (direct or indirect) on the process?
A: yes

Q: Process:  - The salt water is heated - As the saltwater is heated the water becomes a gas - The salt particles sink to the bottom of the container - Gaseous water is piped into another container - Allowed to cool - The salt particles are left behind in the first container - The second container contains fresh water.  Perturbation hypothesis: suppose the heater fails happens, how will it affect less water will become a gas.  Does the supposed perturbation have an effect (direct or indirect) on the process?
A: yes

Q: Process:  - Blood is sent to the liver - The liver uses chemicals and proteins to treat the blood - The blood is cleaned - Energy is produced - The blood leaves the liver cleaned.  Perturbation hypothesis: suppose you Exercise more regularly happens, how will it affect the liver having to work SOFTER.  Does the supposed perturbation have an effect (direct or indirect) on the process?
A:
yes
