Q: Process:  - A conducting metal, like copper, is wrapped around a piece of metal - An electrical source, like a battery, produces an electrical current - The electrical current flows through the wire - The electrical current creates a magnetic field around the wire, magnetizing the metal - The magnetic field can be turned on and off by starting or stopping the electricity source -   Perturbation hypothesis: suppose more copper is available happens, how will it affect a STRONGER electromagnet.  Does the supposed perturbation have an effect (direct or indirect) on the process?
A: yes

Q: Process:  - You breathe in - Diaphragm and other muscles expand to allow room for your lungs to fill - The air flows into the narrow bronchioles in the lungs - From the bronchioles to the alveoli - The oxygen enters into the bloodstream - Is switched with the carbon dioxide in the bloodstream - The carbon dioxide enters through the alveoli - Through the narrow bronchioles - Into the lungs - The carbon dioxide is exhaled out of the body.  Perturbation hypothesis: suppose there is no pressure build up happens, how will it affect less oxygen is taken into the body.  Does the supposed perturbation have an effect (direct or indirect) on the process?
A: no

Q: Process:  - Contact is made with a virus - The virus enters the human or animal body - The virus goes to the part of the body that contains its food - The virus consumes part of the body or materials that the body uses - The virus replicates and spreads - The virus causes symptoms in the body as the immune system tries to expel the virus.  Perturbation hypothesis: suppose a person may be born with a strong immune system happens, how will it affect a person has a stronger immune system.  Does the supposed perturbation have an effect (direct or indirect) on the process?
A: yes

Q: Process:  - Grass and small plants grow in an area - These plants die - The soil gains organic material - The soil becomes more fertile - Larger plants are able to be supported - Trees eventually grow.  Perturbation hypothesis: suppose less pollution in the environment happens, how will it affect MORE forest formation.  Does the supposed perturbation have an effect (direct or indirect) on the process?
A:
