Process:  - You breathe air in - Air enters bronchial tubes - Air is then split into the bronchioles of each lung - Bronchioles have alveoli which are tiny air sacs - Alveoli is surrounded by many small blood vessels - Oxygen passes through alveoli into blood vessels - Blood leaves the lungs as it travels through the body - Blood carries carbon dioxide back to the lungs - Carbon dioxide released when you exhale.  Perturbation hypothesis: suppose You become more addicted to Nicotine happens, how will it affect You smoke more cigarettes.  Does the supposed perturbation have an effect (direct or indirect) on the process?

Answer: yes


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.  Perturbation hypothesis: suppose less air goes into the lungs happens, how will it affect more red blood cells carry oxygen.  Does the supposed perturbation have an effect (direct or indirect) on the process?

Answer: yes


Process:  - Human industry produces chemical compounds - Chemical compounds rise into the air - Chemical compounds mix with elements in clouds - The affected rain falls to the earth - The affected rain can harm natural and man-made objects because of its acidic content.  Perturbation hypothesis: suppose new industry opens happens, how will it affect MORE damage by acid rain.  Does the supposed perturbation have an effect (direct or indirect) on the process?
