Problem: Given the question: Process:  - When water freezes it becomes 10% bigger, or takes up 10% more space - As water expands it puts great pressure on the walls of anything containing it, including any rocks which happen to be surrounding it - The force of the pressure exerted on the rock surrounding it is enough to wedge the walls of the crack farther apart, thus expanding and deepening the crack - Clay expends when wet like ice does - This causes rock to break apart - Some plants like mosses and lichens are capable of growing without soil on bare rock - When they do this their roots penetrate pores and crevices and cause rocks to split apart as the roots force their way down through the rocks -   suppose the rocks are in a climate that does not usuallly experience freezing weather happens, how will it affect LESS or SLOWER erosion of rocks.  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
++++++++++++++++++++++++++++++++
The answer is:
indirectly impacting a step of the process


Problem: Given the question: Process:  - Coal is heated in the boiler - The water tank over the boiler is heated - Creates steam - The steam is funneled to the piston - Piston uses the steam as energy - The piston causes the crankshaft to move.  suppose the fetus is miscarried happens, how will it affect coal is brought to a broiler.  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
++++++++++++++++++++++++++++++++
The answer is:
not impacting any step of the process


Problem: Given the question: 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 animal farming increases pollution 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
