It looks like certain species of earthworms need to surface because they have higher oxygen consumption, while other species do not need to surface because of their lower consumption.
In particular, specimens of Amynthas gracilis were found to have low water tolerance, hence they
crawl out of the waterlogged soil, especially at night when their oxygen ...

The Nernst equation should be:
RT/(zF)*ln(Out/In) = 2.3 RT/(zF)*log10(Out/In)
You substituted for 2.3 RT/F (approximately 60 or 61 mV: use 60 because your instructor asked you to), but forgot about z. Calcium is divalent (and positive) so for calcium z=2. Substitute this and you can see how you get your answer.
(Also note the "out/in" which is how you ...

It can be criticized for the paucity of external sources from which its veracity can be checked. However, although the question is based on a misconception I thought it should be ...
