Process:  - A conducting metal, like copper, is wrapped around a piece of metal - An electrical source, like a battery, produces an electrical current - The electrical current flows through the wire - The electrical current creates a magnetic field around the wire, magnetizing the metal - The magnetic field can be turned on and off by starting or stopping the electricity source -   suppose the Sun gets older 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
Ans: not impacting any step of the process

Process:  - Carbon dioxide enters the leaves through the stomates by diffusion - Water is transported to the leaves in the xylem - Energy harvested through light reaction is stored by forming ATP - Carbon dioxide and energy from ATP are used to create sugar - Oxygen exits the leaves through the stomata by diffusion - The plant reuses the water or the water exits through the stomata as water vapor.  suppose more global warming causes drought happens, how will it affect LESS sugar and oxygen being produced.  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
Ans: directly impacting a step of the process

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 -   suppose higher temperature to water happens, how will it affect piston moves less.  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
Ans: indirectly impacting a step of the process

Process:  - Put the aluminum can into a recycle bin - The cans are transported to a facility - The cans are shredded by a machine - The cans are heated to 1400 degrees to melt them - The molten metal is poured into molds - The molds are flattened and rolled into sheets to reuse.  suppose there are more cans put in bins happens, how will it affect MORE aluminum cans being recycled.  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
