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
Yes, this is true:
Equator runs through the northern part of Lake Victoria (which is on the border between Kenya, Uganda and Tanzania). Specifically, it passes through some islands (the Ssese Islands, some of which are inhabited) on Lake Victoria that belong to Uganda.
As the ocean currents go around, they gather garbage from around the world and bring it to the centre of the pacific ocean where current is proven to be weakest. It can also be found in the Indian ocean and the Atlantic ocean.
