input question: 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 brain tells blood vessels to dilate more happens, how will it affect less body cooling occurring.  Does the supposed perturbation have an effect (direct or indirect) on the process????
output answer: yes
