My question is about this post. I would appreciate it if a few folks with strong biology backgrounds could weigh in.
There are currently three close votes on what appears to me to be a classic SAT-type biology question about osmosis. The reason is "off-topic" because it's not on the list of topics in the Help Center.
Okay I am mystified. An upvoted comment suggests the question would be a "better fit" for physics or chemistry, but I think this is one area in which chemistry, physics, and biology intersect, as a basic understanding of osmosis underlies an understanding of cell membranes.
As far as I know most of the lab experiments in osmosis shown online are associated with first-year biology classes. The topic is covered in physics and chemistry but the underlying thermodynamics is too technical for a first year course and there are other lab priorities.
Have I missed some sea-change in academic thinking about this topic?
Edit: The question is now closed as off topic. I nominated the question to be re-opened and am requesting that it be re-opened by moderator in any event. This closure seems particularly strange given the dearth of clearly articulated college-level biology questions on the site.
