Brittany wants to use a model to study soil erosion on hills. She is told that farmers can prevent soil erosion by plowing so th
Diano4ka-milaya [45]

Answer:

D. set it outside and check on it every day

Explanation:

In order for Brittany to be able to study the soil erosion by using a simplified method of what the farmers do on the slopes to minimize it, she will need to take the pan, leave it outside, and check on it every day. By having the required shape, the soil will give somewhat an example of the soil on the slopes that has been plowed so that the furrows run along the hills. Since the hills do not move or tilt, the pan with the soil should be stable, static. Being put outside, it will be exposed to the natural conditions that cause the erosion, such as the water and wind. Brittany will need to check upon the soil every day and make detailed notes and measurements to see what the erosive effects are on it.

Leokris [45]

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=\frac{DOi-DOf}{fraction}

BOD5 = (10-5)/1

BOD 5 = 5 mg/L
