What happens to the chromosomes when they change from chromatin to chromatids?

chromatin 30 nm in width condenses to form super solenoid chromatin and then chromatid is formed which is of 700 NM in width.

thanks! ;)

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
