Problem: Process:  - The body&#x27;s temperature increases over 98.6 degrees F - The hypothalamus in the brain sends a message to the body - Sweat glands in the skin receive the message - The sweat glands start combining water and chemicals to make sweat - The sweat leaves the skin through pores.  Perturbation hypothesis: suppose more resources available happens, how will it affect less sweet occurs.  Does the supposed perturbation have an effect (direct or indirect) on the process?

A: yes


Problem: Process:  - Bats and other animals produce a high-pitched tone - The sound travels in waves, as sound does - The sound 'bounces' off of a nearby object - The sound wave returns to the bat - The bat hears the echoed sound - Folds in the bat's ear and adaptations in the bat's brain enable it to determine the size, shape, and position of the other object via the properties of the returned sound waves - Other animals use echolocation in generally similar ways -   Perturbation hypothesis: suppose the bat will not be able to locate where it is happens, how will it affect WEAKER echolocation.  Does the supposed perturbation have an effect (direct or indirect) on the process?

A: yes


Problem: Process:  - A forest fire starts - The trees and plants burn - The animals lose their homes - If the animals can not escape, they may die from smoke inhalation - The plants that provide food are gone - The animals have little to eat -   Perturbation hypothesis: suppose everyone had many drinks happens, how will it affect forest is burned down by fire.  Does the supposed perturbation have an effect (direct or indirect) on the process?

A: no


Problem: Process:  - People breathe and expel carbon dioxide - Engines produce carbon dioxide - Living things produce waste - Waste decomposes - Decomposition produces methane - Water evaporates - Water vapor joins the atmosphere - Carbon dioxide, water vapor and methane are greenhouse gases -   Perturbation hypothesis: suppose oil is found in other than Middle Eastern countries happens, how will it affect there are fewer petrol run cars.  Does the supposed perturbation have an effect (direct or indirect) on the process?

A:
yes
