Unresolved complex mixture

So imagine you have a bunch of really small things in a bowl that you can't see very well with your eyes. Some things are round, some are square, some are big, some are small, and they are all mixed together. But when you try to pick out just one thing, you can't really do it because there are so many things all jumbled up together. That's kind of like what an unresolved complex mixture is.

Scientists study things in nature like plants and animals to find out what they are made of and how they work. Sometimes they find a mixture of different things that they can't separate very easily. It's like all the parts of the mixture are tangled up with each other and it's hard to see where one thing starts and another ends. This is called an unresolved complex mixture.

Scientists want to figure out what an unresolved complex mixture is made of so they can understand how it works. They use special tools and machines to try to separate the mixture into its different parts, but it can be really tricky and time-consuming. So scientists are always trying to come up with new ways to study unresolved complex mixtures so we can learn more about the world around us.
