1.) Where is most of the baryonic matter (ordinary matter) of the universe found?(1 point)
> in interstellar gases and stars
> in planets and natural satellites
> in dark matter and dark energy
> in comets and asteroids
2.) When parts of a gas cloud collapse, where does the material first form clumps?(1 point)
> in less dense regions with more space between atoms
> in denser regions with more space between atoms
> in less dense regions with little space between atoms
> in denser regions with little space between atoms
3.) Under the influence of gravity, over time the dense central part of a galaxy will do what?(1 point)
> expand
> stay as it is, forces balanced
> stay the same size but spin more slowly
> contract
4.) How do astronomers know about the future collision of Andromeda and the Milky Way?(1 point)
> All galaxies will collide at some point.
> Astronomers have observed their movements over time.
> The Milky Way has changed course to head toward Andromeda.
> The two galaxies have collided previously.
5.) How are the bars in barred spiral galaxies thought to have formed?(1 point)
> merging
> separation
> primordial collapse
> slow evolution
6.) Which is a mark of a galaxy formed by collapse?(1 point)
> same age stars
> a mix of young and old stars
> uniformly young stars
> abundant gas and dust
7.) Which factors are most likely to affect whether a galaxy will evolve by merging with a second galaxy? Select the two correct answers.(1 point)
O its proportion of gas compared to that of the other galaxy
O its age compared to that of the other galaxy
O its distance from the other galaxy
O its size compared to that of the other galaxy
Here’s the answers took the quiz and got all of them correct.
1. Which factors are most likely to affect whether a galaxy will evolve by merging with a second galaxy? Select the 2 correct answers
- it’s distance from the other galaxy
- It’s size compared to that of the other galaxy
2. Where is most of the baryonic matter of the universe found?
- in interstellar gases and stars
3. When parts of gas cloud collapse where does the material first form clumps?
- In denser regions with little space between atoms
4. How are the bars in barred spiral galaxies thought to have formed?
- Slow evolution
5. How do astronomers know about the future collision of andromeda and the Milky Way?
- Astronomers have observed their movements over time
6. Which is a mark of a galaxy formed by collapse?
- Same age stars
7. Under the influence of gravity, over time the dense central part of galaxy will do what?
- Contract
i got you guys, just took the test. heres the right answers;
1. the GRAVITY of dark matter causes baryonic gas and dust to CLUMP TOGETHER.
2. according to measurements made by the Wilkinson Microwave Anisotropy Probe (WMAP), which material is by far the most plentiful in the universe? DARK ENERGY
3. which types of baryonic matter are most abundant in the universe? Select the two correct answers. HYDROGEN AND HELIUM
Sorry for my son's rudeness, he has anger issues due to me having to be a for a living. My apologies fellow Connection's users ;)
