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 - Question: suppose the fire burns out quickly because it lacks fuel happens, how will it affect the pitch of the sound is lower. How does the supposed perturbation influence the second effect mentioned. Answer by more, less or no effect
Ans: no effect

Process: - Fluid - Waste enters the kidneys - A processing moment in the kidneys let waste and fluid pass - Prevents larger molecules to pass - Fluid goes back to the bloodstream - Bad waste is removed - The final product is turned into urine. Question: suppose if the molecules are too large happens, how will it affect MORE waste being removed from the body. How does the supposed perturbation influence the second effect mentioned. Answer by more, less or no effect
Ans: less

Process: - A stream or river must occur - Through erosion, the stream cuts into the soil and bedrock - Through continuous erosion, a deep gash is cut through - After many years the river may dry up - A dry ravine is left - Question: suppose the flashlight lamp developed a crack. happens, how will it affect LESS or SMALLER ravines forming. How does the supposed perturbation influence the second effect mentioned. Answer by more, less or no effect
Ans: no effect

Process: - The kidneys receive blood from the renal artery - They process it with millions of tiny nephrons - Remove all the waste - The kidneys return the blood back to the body through the renal artery - Send the urine with the waste to the bladder through the ureters. Question: suppose the person is less parched happens, how will it affect LESS waste being removed from the body. How does the supposed perturbation influence the second effect mentioned. Answer by more, less or no effect
Ans: less
