Answer:
The BOD5 for this sample is 5 mg/L
Explanation:
The BOD5 takes into consideration the difference between the initial DO and the final DO divided by the fraction of the sample tested in a 300 mL BOD flask. The problem states that the sample was directly placed in a BOD bottle so we assume that the volume used was 300 mL of the water sample. The fraction of water is 1 (300/300).
BOD5 = (10-5)/1
BOD 5 = 5 mg/L

The Hawaiian Islands are formed on a region of intra plate volcanic activity on the Pacific plate. This region is known as a hot spot. Scientists are not exactly sure what causes this but they do know that a plume of magma rises through the mantle and forces it's way through the crust to form submarine volcanoes and over time volcanic islands.
The magma that rises here originates from the mantle and not crustal melt and so forms basic or basaltic lava.
