Surely you can do this. Just look at them.

Elliptical galaxy is a galaxy having an approximately ellipsoidal shape and a smooth nearly featureless brightness profile. They range in shape from nearly spherical to highly flat and in size from hundreds millions to over one trillion stars. Most Elliptical galaxy are composed of older, low mass stars, with a sparse interstellar medium and minimal star formation actvity. They are surrounded by a large number of globular clusters. They are believed to make up approximately 10-15% of the galaxies in our local Universe. E.g.- MACSG-1423, Maffei 1 .
Elliptical galaxies are normally formed after spiral galaxies merge. The formation is an elliptical mass of stars without any arms. When galaxies merge, the process destroys gasses needed to form new stars. So in an elliptical galaxy we would notice more older stars and less stars in the process of forming.
Don't listen to banana. he is plagiarizing.
Just try your best with the sites provided within the unit and the site Ms. Sue provided above. If you have any further questions, we are more then happy to assist you on this site. Have a nice day! :)
I agree, this is a helping site, not a cheating site. Just try your best guys and if you still need help, just ask and we are here to help! :)
Also, please don't just copy and paste what a site says. In some places, it's a crime, and can at least get you punished.
18. spiral galaxies are bright elliptical galaxies are dim.
Spiral galaxies are hotbeds of star formation but elliptical galaxies aren't nearly as prolific because they contain less gas and dust which means fewer new and brighter stars are born.
19. When meteoroids enter Earth's atmosphere or that of another planet like Mars at high speed and burn up the fireballs or shooting stars are called meteors When a meteoroid survives a trip through the atmosphere and hits the ground it's called a meteorite.
20. Venus is only a 30% closer to the Sun than Earth.
