There are 4 votes to close this question. It's a basic question about entropy and molecule size. Because macromolecules play a big role in biochemical pathways I would have thought the question well within the ambit of biology even if it shares space with chemistry.
If it were a more advanced question this wouldn't be an issue. The OP muddied the waters a bit by cross-posting [correction: posting question identical to one ] at the Chemistry site. Also the question itself is badly articulated. Nonetheless it appears to be another garden-variety SAT type question which could be asked/answered in any basic science forum.
If the question is closed I will vote to re-open but am asking once again if someone could venture an opinion. Perhaps a moderator could look at it and make a call?
When it comes to the creationist questions I am all for a low threshold but does it make sense to close basic science questions that come up in any 1st year bio course?
