input: Please answer the following: Process:  - A tree produces seeds - The seeds are dispersed by wind, animals, etc - The seeds reach the ground - Grow into new trees - These new trees produce seeds - The process repeats itself over and over -   Perturbation hypothesis: suppose seeds do not reach the ground happens, how will it affect MORE forest formation.  Does the supposed perturbation have an effect (direct or indirect) on the process?
++++++++++
output: yes


input: Please answer the following: Process:  - Air enters the nose or mouth and travels through the windpipe into the lungs - The lungs have a series of smaller and finer tubes and sacs - Air reaches the smallest and finest air sacs called alveoli - Oxygen travels from the alveoli into the blood - Oxygen-rich blood is carried to the heart - Oxygen-rich blood is pumped throughout the body by the heart - Cells take in the oxygen rich blood and release carbon dioxide rich blood - The carbon dioxide rich blood travels to the lungs - Carbon dioxide travels through the throat and is exhaled.  Perturbation hypothesis: suppose a person may be very unwell 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?
++++++++++
output: yes


input: Please answer the following: 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 less virus enters the body 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?
++++++++++
output: no


input: Please answer the following: Process:  - Acid rain makes waters acidic - Causes them to absorb aluminum from soil - The water runs off from the soil into lakes, streams, etc - Fish and their eggs die - Frogs and plants die - Insects and other wildlife die - The ecosystem is out of balance, causing further problems -   Perturbation hypothesis: suppose there is increase of acid in the air happens, how will it affect MORE damage by acid rain.  Does the supposed perturbation have an effect (direct or indirect) on the process?

output:
yes
