Question

Jake and Aisha conducted an experiment together to test the effects of fertilizer runoff on the amount of dissolved oxygen in a lake. They each created a graph from the results. mc021-1.jpg mc021-2.jpg Graph 1: Jake’s Graph Graph 2: Aisha’s Graph Jake concluded that the runoff had little effect on the dissolved oxygen levels, and Aisha concluded that the runoff had a major effect on dissolved oxygen levels. What is the most likely reason that Jake and Aisha formed different conclusions? Each person used different references for comparison. Jake recorded the wrong measurements on two days. Aisha converted the units before creating her graph. The students used different ranges for their y axes.

Answer 1

Explanation:

From the question, it is evident that Jake measured wrong for the two days. She forgot to check the units. Jake’s graph shows that she took a different range for her Y axis, but Aisha took another variable.

So, Aisha got the desired answer which matches the practical findings. But Jake firstly forgot to convert the units before plotting the same in the graph. And secondly, she used different ranges for her Y-axis. Which leads to different answers.

Answer 2

Answer:

the answer is B

Explanation:
