Problem: 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.  suppose a person was born with low immunity happens, how will it affect a person will get many infections.  Which of the following is the supposed perturbation?  - directly impacting a step of the process - indirectly impacting a step of the process - not impacting any step of the process

A: indirectly impacting a step of the process


Problem: Process:  - You breathe air in - Air enters bronchial tubes - Air is then split into the bronchioles of each lung - Bronchioles have alveoli which are tiny air sacs - Alveoli is surrounded by many small blood vessels - Oxygen passes through alveoli into blood vessels - Blood leaves the lungs as it travels through the body - Blood carries carbon dioxide back to the lungs - Carbon dioxide released when you exhale.  suppose isotope is more stable happens, how will it affect MORE oxygen being brought to the body.  Which of the following is the supposed perturbation?  - directly impacting a step of the process - indirectly impacting a step of the process - not impacting any step of the process

A: not impacting any step of the process


Problem: Process:  - A male and female bird mate - The female lays eggs - The eggs are incubated by the parents, by sitting on them, for weeks - The bird hatches from an egg - The parents feed them as the continue to grow - Develop flight feathers - The parents teach them to fly - After learning to fly they leave the nest to live on their own - The next year they breed beginning the cycle again -   suppose the eggs incubate less safely happens, how will it affect there are less birds that grow into adults.  Which of the following is the supposed perturbation?  - directly impacting a step of the process - indirectly impacting a step of the process - not impacting any step of the process

A: indirectly impacting a step of the process


Problem: Process:  - You find an empty ice cube tray - You fill the tray with warm water - You carefully place the tray on an even surface in a freezer that is at least 32 degree Farhenheit, the freezing point of water - The water begins to get colder until it starts to freeze solid - The water expands as it freezes, one of the few liquids that has greater volume as a solid - Because you used warm water, the gasses in the water had evaporated out, so you will have nice clear ice cubes without cracks from the trapped gasses -   suppose there is less water available happens, how will it affect LESS ice cubes being made.  Which of the following is the supposed perturbation?  - directly impacting a step of the process - indirectly impacting a step of the process - not impacting any step of the process
