Question

Phoebe is taking samples from a lake to determine how the populations of aquatic life change during the summer. Each week for a month she takes samples from different areas of the lake. Over the course of a month, she finds the marine life listed in the chart below. What should Phoebe change about her methodology to better address her question?

Answer 1

Answer: Take samples from the same location each time.

*(IF)* this is in refrence to this chart (I will link it) then it would be (B) Take samples from the same location each time.

Explanation:

I took the test

Answer 2

This question is incomplete

Step-by-step explanation:

However, the main thing she needs to "change" in her methodology is to take samples from different lakes instead of taking samples from the same lake. This is because it is possible there are other factors affecting the population growth in that lake which might not be affected by the summer season.

Another thing Phoebe might want to look at is the possibility of conducting this experiment during other seasons (like winter or spring), to be sure what she is experiencing is actually as a result of the season.
