Process: - An enzyme in saliva begins to break down carbohydrates - Food is squeezed down the esophagus when you swallow - Acid and enzyme in the stomach break the food down - Releases nutrients - Food then pumped into small intestine - Fluid and enzymes from liver and pancreas pumped into small intestine - Help break food into smallest molecules - Nutrients pass through wall of small intestine - Nutrients absorbed into blood stream - Unused materials passed into large intestine to become fecal matter. Perturbation hypothesis: suppose person has an overeating disorder happens, how will it affect MORE food being digested. Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: yes

Process: - The liver removes toxins from the blood - Liver also cleans blood that has just been enriched with vitamins and minerals during digestion - Liver processes the good stuff into forms that the rest of the body can use - Waste or stuff your body doesn't need can be carried by bile back into the intestine or into the kidneys - The liver also produces a digestive juice called bile that helps the body absorb fat into the bloodstream - The liver also stores extra carbohydrates as glycogen for the body to use as fuel when needed. Perturbation hypothesis: suppose person doesn't feel like eating happens, how will it affect the liver having to work SOFTER. Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: no

Process: - Plants start growing on or near the rocks - The roots of the growing plants start to break up the rock - The plant acids dissolve the rock - The rock is broken down into smaller pieces - Erosion begins. Perturbation hypothesis: suppose more global warming occurs happens, how will it affect Less plants grow on the rocks. Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: no

Process: - Particles in the environment interact with rocks - The particles remove small pieces of the rock each time they touch the rocks - The particles continue to hit, brush against, or grow against the rocks - The rock eventually is broken apart by this contact - The pieces of the rock are now small rocks - The rock pieces are worn away into smaller and smaller pieces by the same forces - Perturbation hypothesis: suppose stronger batteries used happens, how will it affect harder force of particles against rock. Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: no
