Answer:
Both early protostars and young stars are formed from a clod of gas which collapses under gravity to form a star. Both types of star are mainly Hydrogen and some Helium. They would be 75% Hydrogen, 25% Helium with traces of Lithium. Young stars formed out of the remains of old stars would still be mainly Hydrogen. Another way to say it is Both types of star are mainly Hydrogen and some Helium. Early protostars would have been formed from the gasses that were created soon after the big bang. They would be 75% Hydrogen, 25% Helium with traces of Lithium. Young stars formed out of the remains of old stars would still be mainly Hydrogen.

Hierarchy and balance are both principles that are taken into account when making a map. They are important parts of cartography for different reasons.
Hierarchy has to do with combining the many types of features, names, information, and landmarks that are found on the map. A proper hierarchy is necessary so that the elements which need to be visible seem more important.
Balance is an even more visual concept since it deals with the aesthetically pleasing aspect of the map. A well-balanced map will have the map element of the map near the center and will have strategically placed legends and titles that do not take away from the overall depiction of what is being mapped.
Copernican heliocentrism<span> is the name given to the astronomical </span>model<span> developed by </span>Nicolaus Copernicus<span> and published in 1543. It positioned the </span>Sun<span> near the center of the </span>Universe<span>, motionless, with Earth and the other planets rotating around it in circular paths modified by epicycles and at uniform speeds. The Copernican model departed from the </span>Ptolemaic<span> system that prevailed in </span>Western culture<span> for centuries, placing Earth at the </span>center of the Universe<span>, and is often regarded as the launching point to modern </span>astronomy<span> and the </span>Scientific Revolution.
