Problem: Process: - Air enters the lungs through bronchial tubes - Air enters bronchioles - Bronchioles have tiny air sacs called alveoli - Alveoli surrounded by small blood vessels - Oxygen absorbed by small blood vessels - Vessels deliver oxygen to every cell in the body - Blood brings carbon dioxide back to lungs - Carbon dioxide released when you exhale. Perturbation hypothesis: suppose smoke filled air happens, how will it affect more oxygen for blood vessels. Does the supposed perturbation have an effect (direct or indirect) on the process?

A: yes

Problem: Process: - Wind passes the turbines and moves the blades - The shaft of the turbine spins - Shaft is connected to a generator - The generator uses the spins of the shaft to rotate a rotor - The rotor spins inside the core, which has magnets inside surrounded by wire loops inside - The spinning of the rotor in the core generates electricity - Perturbation hypothesis: suppose more structure obstructions happens, how will it affect MORE electricity being generated. Does the supposed perturbation have an effect (direct or indirect) on the process?

A: yes

Problem: Process: - The coffee pot is filled with water - Water is poured into the well of the machine - A filter is placed in the basket - Ground coffee is measured into the filter - Turning on the machine starts the water heating - The hot water rises up - The water drops into the ground coffee - The hot water passes through the grounds - The coffee drips into the pot from the basket. Perturbation hypothesis: suppose coffee machine is working fine happens, how will it affect pour water into coffee machine. Does the supposed perturbation have an effect (direct or indirect) on the process?

A: yes

Problem: Process: - Air is pulled into the lungs - Oxygen moves from the lungs into the bloodstream - Air is pushed through the vocal chords - A person talks - Other air is pushed out of the lungs into the environment. Perturbation hypothesis: suppose there was no forest in the area happens, how will it affect a SMALLER amount of oxygen being delivered to the blood stream. Does the supposed perturbation have an effect (direct or indirect) on the process?

A:
no
