Process: - A can is thrown away into a recycling bin - The can is taken to a recycling center - Melted down along with other cans - The melted metal is turned into bars - Becomes material for other products. Perturbation hypothesis: suppose more pits are opened happens, how will it affect MORE aluminum cans being recycled. Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: no

Process: - Body temperature rises - The brain tells blood vessels to dilate - The sweat glands become active - Moisture is released from the pores - The moisture evaporates - The evaporation causes cooling. Perturbation hypothesis: suppose less moisture is released from the pores happens, how will it affect LESS body cooling occurring. Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: yes

Process: - Bees find a place for the hive, such as a rock crevice or tree branch - Bees gather nectar from flowers - The bees evaporate the nectar by passing it back and forth to each other - The evaporation turns the nectar into sugary honey - The bees chew the honey until it turns into moldable wax - The bees mold the wax into hexagonal (six sided) cylinders - Thousands of these hexagonal cylinders put together form the hive - Perturbation hypothesis: suppose flowers are recieving the correct nutrients happens, how will it affect Bees will extract less nectar from the flowers. Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: yes

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 there is too much residual noise happens, how will it affect WEAKER echolocation. Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: yes
