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 the bronchial tubes are working properly happens, how will it affect a GREATER amount of oxygen being delivered to the blood stream. Does the supposed perturbation have an effect (direct or indirect) on the process?

A: yes

Problem: Process: - The sun gives off radiation - The radiation is aborbed by the Earth - Some of the radiation goes back into space - Some is trapped by the atmosphere - If too much heat is trapped - Global warming occurs. Perturbation hypothesis: suppose Intense solar activity strips the atmosphere from the earth happens, how will it affect Less heat is trapped by the atmosphere. 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 a person will become more ill happens, how will it affect MORE bad effects of pollution. Does the supposed perturbation have an effect (direct or indirect) on the process?

A: no

Problem: Process: - Animals and plants die in soft soil or mud - Sediment builds up over the remains - The remains decompose, leaving only trace amounts - The remaining parts over the years are replaced with mineral - A fossil is formed - Perturbation hypothesis: suppose There is heavy rain happens, how will it affect more sediment builds up over the remains. Does the supposed perturbation have an effect (direct or indirect) on the process?

A:
no
