For the diagram below, a siren is going off in the distance to the left. The diagram shows the diffraction of the siren's sound wave around the wall. If you were behind the wall (position labeled "X") what would you hear? wall spurd waves for source to the left, moving to the right. X O A. You would hear the siren, but the pitch would sound higher. O B. You would hear the siren and think it was located at the opening in the wall. O C. You would not hear anything because there is no sound wave at that position. O D. You would not hear anything, because the wall would block the sound of the siren.​

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.
