Ablock of wood has a small metal disk attached to one side, small enough that the average density of the block is still less than the density of water. if you carefully place the block into water with the metal disk on top and so out of the water then it will float. if you now turn the block over so that the metal is on the bottom and so in the water will the block still float, and if so will it float at the same level, or higher, or lower? (don’t forget to justify your answer.)

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.
