Are there ways to apologize without actually saying "I'm sorry"?

Say, you did something wrong, argued about it, made it a big deal… and now stuck in a big situation that could just get worse. What are ways of apologizing to someone without straight out saying that?
ex)Argument/ fight with mom, acted up, gave attitude… and apologizing isn’t something to do in this situation, because she doesn’t exactly take apologies.
(sorry it’s really not very specific, but i don’t really want to talk about it, but with the info given what would you do to apologize?)
