Process: - Air goes into the lungs - The lungs remove oxygen from the air - Oxygen diffuses from alveoli in the lungs to the bloodstream - Hemoglobin in red blood cells attaches to the oxygen - Red blood cells carry oxygen all around the body - Oxygen diffuses into cells from capillaries. Question: suppose less oxygen reaches the lungs happens, how will it affect LESS oxygen being brought to the body's cells. How does the supposed perturbation influence the second effect mentioned. Answer by more, less or no effect
Ans: no effect

Process: - A red giant burns mass - This mass creates high core temperatures - The mass decreases - The red giant can no longer fuse the carbon and oxygen in its center - The gravity of the star can no longer hold the outside layers - The layers break away - Only the inner core remains - This inner core is known as a white dwarf. Question: suppose part of the inner core melts happens, how will it affect the inner core will be smaller. How does the supposed perturbation influence the second effect mentioned. Answer by more, less or no effect
Ans: more

Process: - Pollution enters natural water sources such as rivers and lakes - The pollution negatively affects the water quality - The pollution negatively affects the health of plants and animals - The plants and animals have shorter, less healthy lives - The plants and animals do not reproduce very well - The number of plants and animals decreases over time - The quality of water gets worse and worse as there are no plants or animals to clean it - Eventually there is nothing living in the water and it is unusable - Question: suppose regulations against pollution might be relaxed happens, how will it affect there will be fewer pollutants pumped into rivers. How does the supposed perturbation influence the second effect mentioned. Answer by more, less or no effect
Ans: less

Process: - Ocean waves hit land - Ocean water pulls sand off of beaches - Ocean water breaks rocks off of cliffs - Ocean water carries sand and rocks into the ocean - Sand and rocks go to other land or the bottom of the ocean. Question: suppose More sand is pulled off the beaches happens, how will it affect LESS erosion by the ocean. How does the supposed perturbation influence the second effect mentioned. Answer by more, less or no effect
Ans: less
