Please answer the following question: 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 -   suppose the bat will not be able to locate where it is happens, how will it affect WEAKER echolocation.  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:
directly impacting a step of the process
