Answer:
disk component: the flat disk in which stars follow orderly, nearly circular orbits around the galactic center (contains interstellar medium, gas and dust and star formation here) .
spheroidal component: the bulge and the halo.
Disk component includes cool gas and active star formation.
Step-by-step explanation:
Spiral galaxies have three main components: a bulge, disk, and halo.
The disk component of a spiral galaxy mostly consists of the gas and the dust. The disk typically has younger stars and also have active star formation. The disk forms arm structures. Our Sun is located in an arm of our galaxy, the Milky Way.
The bulge is a spherical structure found in the center of the galaxy. This feature mostly contains older stars.
The halo of a galaxy is a loose, spherical structure located around the bulge and some of the disk. The halo contains old clusters of stars, known as globular clusters.
