Problem: Process:  - A person breathes in oxygen - The oxygen passes through the bronchial tubes to the lungs - The oxygen is moved into the bloodstream - Circulates through the body - The cells in the body exchange the oxygen with carbon dioxide - The bloodstream carries the carbon dioxide back to the lungs - The lungs expel the carbon dioxide through the nose and mouth.  Perturbation hypothesis: suppose there is breathable air happens, how will it affect the lung is not healthy.  Does the supposed perturbation have an effect (direct or indirect) on the process?

A: yes


Problem: Process:  - Air is brought in through the mouth - Passes through the lungs - And into the bronchial tissue - The carbon dioxide is removed - The lungs bring the oxygen to the rest of the body.  Perturbation hypothesis: suppose coal is banned happens, how will it affect lung is cleaned of carbon dioxide.  Does the supposed perturbation have an effect (direct or indirect) on the process?

A: no


Problem: Process:  - Boil salt water - The water will turn into water vapor - Collect the water vapor - Allow the water vapor to cool - The water vapor will turn into liquid water - The salt will be separated from the water.  Perturbation hypothesis: suppose it is tropical storm season happens, how will it affect LESS salt being removed from the water.  Does the supposed perturbation have an effect (direct or indirect) on the process?

A: no


Problem: Process:  - Put water in an ice cube tray - Put the ice cube tray in the freezer - Wait 5 to 6 hours - Take the ice cube tray out of the freezer - Bend the tray slightly to get the ice cubes out and into a drink.  Perturbation hypothesis: suppose drinking more water happens, how will it affect tray will be put into a freezer.  Does the supposed perturbation have an effect (direct or indirect) on the process?

A:
no
