Please answer this: 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 is in a field happens, how will it affect less sound waves return to bat.  Does the supposed perturbation have an effect (direct or indirect) on the process?

Answer: yes


Please answer this: Process:  - Air is taken into the body via the nose or mouth - The air travels into the windpipe - The windpipe divides the air to the two lungs via the bronchial tubes - The lungs oxygenate the blood in the body - Carbon dioxide is filtered out by every cell in the body - The carbon dioxide is carried back to the lungs via the bloodstream - The carbon dioxide is exhaled.  Perturbation hypothesis: suppose the lung is not healthy happens, how will it affect there is no air in the area.  Does the supposed perturbation have an effect (direct or indirect) on the process?

Answer: yes


Please answer this: Process:  - Solution caves are formed in limestone and similar rocks by the action of water - After a rain, water seeps into cracks and pores of soil and rock - The water percolates beneath the land surface - Some of the water reaches a zone where all the cracks and pores in the rock are already filled with water - Rainwater absorbs some carbon dioxide as it passes through the atmosphere and even more as it drains through soil and decaying vegetation - The water combines chemically with the carbon dioxide - A weak carbonic acid solution is formed - This acid slowly dissolves calcite, forms solution cavities, and excavates passageways -   Perturbation hypothesis: suppose more water reaches a zone already filled with water happens, how will it affect MORE salt being removed from the water.  Does the supposed perturbation have an effect (direct or indirect) on the process?
