[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.  suppose dishes a well rinsed happens, how will it affect more sunlight available.  Which of the following is the supposed perturbation?  - directly impacting a step of the process - indirectly impacting a step of the process - not impacting any step of the process
****
[A]: not impacting any step of the process


[Q]: 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.  suppose more water freezes into ice happens, how will it affect LESS or SLOWER weathering occurring.  Which of the following is the supposed perturbation?  - directly impacting a step of the process - indirectly impacting a step of the process - not impacting any step of the process
****
[A]: directly impacting a step of the process


[Q]: Process:  - Electromagnet creates magnetic field with electricity - Conductive copper wire is wrapped around a piece of metal - An electric current gets introduced from power source - Flows through the wire - Magnetic field gets created in the wire - And the metal gets magnetized - When turned off it is no longer magnetic.  suppose less current flows through wire happens, how will it affect a WEAKER electromagnet.  Which of the following is the supposed perturbation?  - directly impacting a step of the process - indirectly impacting a step of the process - not impacting any step of the process
****
[A]: directly impacting a step of the process


[Q]: Process:  - Water is heated - The heated water evaporates - The salt is left behind - The evaporated water condenses on a cold surface - The evaporated water is collected - The process is repeated - More salt is removed from the water.  suppose there is not much water available happens, how will it affect a lesser volume of water is heated.  Which of the following is the supposed perturbation?  - directly impacting a step of the process - indirectly impacting a step of the process - not impacting any step of the process

[A]:
indirectly impacting a step of the process
