Astronomers suspect that a galaxy’s type can be affected both by the conditions in the protogalactic cloud from which it forms ("initial conditions") and by later interactions with other galaxies.
each item below describes either a condition in a protogalactic cloud or a later interaction.
match these items to the galaxy type you would expect to form as a result.
1. stars form rapidly as the protogalactic could shrinks.
2. most protogalactic gas settles into a disk.
3. protogalactic cloud has high density.
4. a galaxy collision strips away gas.
I will provide the matching galaxy type for each term
1. stars form rapidly as the protogalactic could shrinks. --> this is something from an elliptical galaxy
2. most protogalactic gas settles into a disk. --- > this belongs to a Spiral galaxy, thats why the gas settles as a disk
3. protogalactic cloud has high density. --> this belongs to the elliptical galaxy group
4. a galaxy collision strips away gas. --> elliptical as well
In elliptical galaxies, the protogalactic cloud has high density, also the stars form rapidly as the cloud shrinks, meanwhile in an elliptical galaxy, the gas settles into a disk
All the provided options are correct
Galaxies are the broad and flat system of disc in which the solar system, planets, sun along with interstellar gas and dust particles are held by the force of gravitation.
Galaxies when occurs in multiple numbers, are considered to be galaxy groups and this galaxies can merge with one another and rapidly moving away due to the expansion of the universe since the big bang explosion.
When galaxies of equal mass collides then it forms elliptical galaxies, but when two galaxies of unequal mass collides with each other, then the bigger massive galaxies does not undergo changes in shape but the smaller galaxies gets significantly affected.
When galaxies collides with one another it forms a tail, due to the reaction between the interstellar gas and dust particles that are present in the space, and are known as the tidal tail and the galaxies that are huge and massive have numerous number of satellites.
Thus, all options are correct.
D. Galaxies typically contain billions of stars.
A galacy on average contains from 150-250 billion up to 100 trillion of starts, for example the milky way has aproximately 200 billion stars, there are for example andromeda galaxy has approximately 1 trillion stars but the largest observable and found galaxy in the universe is IC1101 has a mass of 100 trillion stars and this is only what we have been able to observe.
Option D and E are True.
Explanation:Tidal streams can result from galaxies as a result of interaction between the galaxies due to the gravitational force. While the interaction is going on, stars and gas from the outer most part of the galaxies are usually cut off resulting in the formation of 2 tidal tails out of which one trails and the other one preceeds each galaxy.The largest galaxies like our Milky way galaxies tend to have satellite or smaller galaxies which are bound due to gravitational force as a part of the sub group of larger galaxy which itself is a part of the Local group i.e., local galaxy cluster
the answer is D i took the quiz so it is definitely D
The items here are describing either a condition in a later interacton or a protogalactic cloud. The results matching with spiral and elliptical galaxy are:
For spiral galaxy are options 6,3,2 and 5.
and for elliptical galaxy are options 4 and 1.
Here it is given that astrnomers suspect that types of galaxy can be affected both by the conditions which occurs due to protogalactic cloud and then from it forms the initial conditions and then by the later interactions with the other galaxies.
so, both types of galaxies are matched with their respective items given:
A. Spiral galaxy:
2. A galaxy collision results tostripping of gas.
3. The protogalactic cloud rotates in a very slow motion.
5. The density of protogalactic cloud is very high.
6. when the protogalactic cloud shrinks cloud forms very rapidly.
B. Elliptical galaxy:
1. The protogalactic cloud has high angular momentum.
4. Most of the protogalactic gases settles down into a disk.
Small galaxies outnumber small galaxies, but large galaxies produce most of the light in the universe.
