Answer:
Stars are the basic building blocks of galaxies.
Explanation:
Stars are the dense embedded structures formed in compact in clusters. They range from a dozen to million of stars.These are he observational indicators of the gas expulsion from clusters which may occur even quicker or late than a stellar crossing time scale or within. They are classified into two main groups: OCs and globular clusters
OCs: They are ranging from few tens of millions of years old.They are generally young objects. They are less tightly bounded by the gravity. & less densely populated.
Globular Clusters: These are a tight compositions/ formation of old stars which are distributed roughly in the galactic halo spherically i.e.around the galactic center. Around the galactic centers they are having a high elliptical orbits.
