Answer:

Elements

Explanation:

Elements such as those on the periodic table are unable to be broken down into simpler forms.

Mixtures (both homogenous and heterogenous) are made of multiple elements making it able to be physically broken down back to its original elements.

Compounds are also made up of multiple elements, however it must go through a chemical separation process in order for it to be broken down into its original elements.

Matter is a broad term of any substance. So it could both be a combination or a single element making it incorrect for this question.

On Monday while Johnny was getting ready for school, he was in the bathroom holding his comb when he got an itch on his head. Jo

I'd say that his comb has a static electricity charge. It can either be negative, or positive. Let's just say it's positive, and the water is negatively charged. This means that it will affect the water flow when the two charges meet. I hope this helps! ~Mia
