Can I-485 get denied?

I would appreciate if someone can answer this. If my I-140 gets approved, is there any possibility that my I-485 can get denied?

It is possible, but not many tho..... Also, if your I-485 is denied, you may be able to file another I-485, depending on the circumstances. Or you can go with Immigrant Visa Processing to get a GC.
