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?

Provide details about the creatures in the "other" category.

Take samples from the same location each time.

Collect samples from nearby lakes for comparison.

Use a more sophisticated net to collect smaller creatures.

Answer 1

Ok lets see here

Answer 2

I think the question is B.

Answer 3

it's not C...

Answer 4

Oh their is a picture O_O

Answer 5

I change my answer it is maybe A.

Answer 6

maybe?? thats not encouraging....

Answer 7

lol

Answer 8

Thats how you should do a trial if you want to find out populations of aquatic life change during the summer you need to do this to make your data accurate and too see the population difference.

Answer 9

answer anyone?

I think I agree with the music thief ...

Answer 11

Answer 29

This is a crap question. You would take samples from a set of locations, chosen randomly, and you should also do a mark/release sampling to estimate population size as well as species diversity.

Answer 30

Nothing is a crap question.

Answer 31

@SolidIceCream, Let me explain. First, I apologize if my statement "...crap question" was taken as meaning something akin to, "What a stupid question to ask." What I meant was, that if this was a question that a teacher gave a student, it is vague enough that I would expect students to have an extremely difficult time answering the question. Why, because nearly all the choices could be valid.

Of course she should provide details about the "other" creatures; they are part of the lakes fauna.

She should definitely take samples from the same places, and those should be randomly selected. However, given that it is a lake the marine* life is stuck in there and randomly selected locations that are different than the resampled locations may help account for migration within the lake.

Comparisons of near by lakes could be potentially useful, or may not be. It should be investigating though to make the decision to sample it or not.

Finally, she should absolute use the best equipment to catch as many organisms as possible since she is trying to examine all the organisms.

*Marine life refers to the organisms in the oceans and seas, not freshwater lakes.

Answer 32

@mrdoldum Ok I agree with what you are saying and you explained it very well I did not mean to insult you in anyway if I did than I am sorry myself.

Answer 33

@SolidIceCream, no worries. I should have explained myself better in the first post. When I ask students questions like these I try to be very explicit because of the issues I described above (I am a PhD candidate and teach introductory biology labs, botany/mycology labs, and microbiology labs).
