Students want to determine the impact of soil erosion from the development of new housing. They plan to measure the density of a species of algae growing along the bottom of a river that flows through their town. The town is built in a heavily forested area, but a large area of trees along the river was recently clear-cut to allow for the construction of a new housing development. which has caused exposed soil to wash into the river. The river flows north to south through the town and is still forested both up and downstream of the town. Which of the following would be the best control sample for the study?

A sample of water collected just downstream of the northern forest

A student group is involved in a restoration study of a nearby disturbed area. They decide to collect six soil samples and analyze them for carbon (C) and nitrogen (N). Two of the samples are found to be very high in C and N, but the other four samples are low in both. The students also notice that the color of the two soil samples that are high in C and N is very dark. Which of the following is the most likely explanation of the data?

Two of the samples were collected
