Problem: Process:  - Your thermostat senses that the room temperature has fallen below your thermostat setting - Your thermostat sends a signal to your heating system to provide heat for your home - When your oil burner is engaged, heating oil travels from the tank to the burner by way of a pump - Here the oil becomes a fine mist mixed with air - The fuel/air mixture is then injected into the burner where it is ignited in the combustion chamber - The warm air is disbursed through vents, hot water through baseboards, or by steam radiators -   Perturbation hypothesis: suppose the room has less heat happens, how will it affect MORE heat for the house.  Does the supposed perturbation have an effect (direct or indirect) on the process?

A: yes


Problem: Process:  - Carbon dioxide from the air passes through small pores (holes) in the leaves - These pores are called stomata - Water is absorbed by the roots and passes through vessels in the stem on its way to the leaves - Chlorophyll absorbs the sun&#x27;s energy - It is this energy that is used to split water molecules into hydrogen and oxygen - Oxygen is released from the leaves into the atmosphere - Hydrogen and carbon dioxide are used to form glucose or food for plants.  Perturbation hypothesis: suppose more limestone on environment happens, how will it affect LESS sugar and oxygen being produced.  Does the supposed perturbation have an effect (direct or indirect) on the process?

A: no


Problem: Process:  - Acid rain is produced by chemicals that reach into the atmosphere - Falls onto the ground - The acid rain starts scouring rocks - Destroys vegetation - The lack of vegetation alters the surrounding environment.  Perturbation hypothesis: suppose less acid rain will be produced happens, how will it affect LESS damage by acid rain.  Does the supposed perturbation have an effect (direct or indirect) on the process?

A: yes


Problem: 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 -   Perturbation hypothesis: suppose the water is broken down happens, how will it affect there is an increase in pollution.  Does the supposed perturbation have an effect (direct or indirect) on the process?

A:
yes
