Process: - A virus enters a host body - The virus has receptors that lock onto a target cell - The virus enters the cell - The virus uses the cell like a factory to make new copies of the virus - The new copies of the virus leave the cell - Infect other cells - The host gets sick as its cells are damaged. Perturbation hypothesis: suppose the person is very run down happens, how will it affect a GREATER spread of the virus. Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: yes

Process: - Forest fires burn forests - The animals living in the forest have fewer places to hide - Predators can now find their prey eaiser - Birds will fly away from the area - Waters warm up which hurts the fish swimming in them. Perturbation hypothesis: suppose some people commit arson happens, how will it affect a SMALLER negative effect on animals. Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: yes

Process: - Plants and animals long ago died - They are buried under layers of soil - Pressure builds over time - The remains liquefy - The carbon atoms rearrange to become a new substance. Perturbation hypothesis: suppose the area is very geographically stable happens, how will it affect More pressure builds. Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: yes

Process: - The earth develops cracks deep beneath the surface - The cracks get very long and big in some places - The earth places pressure against the rocks on both sides of the cracks - The pressure causes the rocks to press against each other very hard - The cracks continue to develop - The earth moves against itself on both sides of the cracks - The pressure and movement around the cracks causes the rocks to crumble in some places - A lot of energy is released - The energy causes seismic waves - The seismic waves move the earth in an earthquake. Perturbation hypothesis: suppose less oxygen in the environment happens, how will it affect rocks press harder against each other. Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: no
