Categorize galaxies as spiral, elliptical and irregular. You may use each response more than once. (1 point)

Question

These galaxies have unusual shapes.
In this galaxy, the arms have many young stars and the central region has older stars.
80% of the galaxies in the universe.
The Milky way galaxy.
Andromeda galaxy, our closest neighbor.
Shaped like spheres or cucumbers and contain old stars.
:: spiral
:: elliptical
:: irregular

Answer 1

1. These galaxies have unusual shapes.
   :: irregular

2. In this galaxy, the arms have many young stars and the central region has older stars.
   :: spiral

3. 80% of the galaxies in the universe.
   :: elliptical

4. The Milky Way galaxy.
   :: spiral

5. Andromeda galaxy, our closest neighbor.
   :: spiral

6. Shaped like spheres or cucumbers and contain old stars.
   :: elliptical

Answer 2

80% was wrong

Answer 3

I apologize for the error. Here’s the corrected categorization:

1. These galaxies have unusual shapes.
   :: irregular

2. In this galaxy, the arms have many young stars and the central region has older stars.
   :: spiral

3. 80% of the galaxies in the universe.
   :: elliptical

4. The Milky Way galaxy.
   :: spiral

5. Andromeda galaxy, our closest neighbor.
   :: spiral

6. Shaped like spheres or cucumbers and contain old stars.
   :: elliptical

Since 80% of galaxies in the universe are actually spiral galaxies, the correct response for item 3 should be: 3. 80% of the galaxies in the universe.
:: spiral

Thank you for your understanding, and I appreciate your patience!

Answer 4

Place each item in the correct order. (1 point)
The third planet from the sun.
This is is the fourth planet from the sun in the solar system and is a terrestrial planet with a reddish color.
This is a terrestrial planet and the innermost and smallest planet in the solar system, orbiting the sun once every 88 days.
The second-closet planet to the sun, it is also classified as a terrestrial planet
and it is sometimes called
Earth's "sister planet"
because the two are similar in size, gravity, and composition.
This is the fifth planet from the Sun and is the largest one in the solar system, containing more matter than all of the other planets combined.
This is the sixth planet from the Sun and the second largest planet in the Solar System, after Jupiter and is one of the four Jovian planets.
This is the eighth and farthest planet from the sun in the solar system.
This is the seventh planet from the sun and the third-largest and fourth-most massive planet in the solar system.
:: mars
』
:: uranus
:: Earth
• mercury
:: neptune :: venus : jupiter
:: saturn

Answer 5

Here’s the correct order of the items based on their position from the Sun:

1. This is the innermost and smallest planet in the solar system, orbiting the sun once every 88 days.
   :: mercury

2. The second-closest planet to the sun, it is also classified as a terrestrial planet and is sometimes called Earth's "sister planet" because the two are similar in size, gravity, and composition.
   :: venus

3. The third planet from the sun.
   :: Earth

4. This is the fourth planet from the sun in the solar system and is a terrestrial planet with a reddish color.
   :: mars

5. This is the fifth planet from the Sun and is the largest one in the solar system, containing more matter than all of the other planets combined.
   :: jupiter

6. This is the sixth planet from the Sun and the second largest planet in the Solar System, after Jupiter and is one of the four Jovian planets.
   :: saturn

7. This is the seventh planet from the sun and the third-largest and fourth most massive planet in the solar system.
   :: uranus

8. This is the eighth and farthest planet from the sun in the solar system.
   :: neptune

So, the order is: mercury, venus, Earth, mars, jupiter, saturn, uranus, neptune.

Answer 6

Fill in each blank to complete each statement (1 point)
The sun-centered system of planets developed by Copernicus is an example of
a(n),
model.
Kepler discovered that the orbit of each planet is a(n)
rather than a perfect circle.
An Earth-centered system of planets is known as a(n)
model.
:: Ancient Greek
:: Ptolemy's Geocentric
•: Copernicus's Heliocentric

Answer 7

Here is the completion of each statement:

1. The sun-centered system of planets developed by Copernicus is an example of a(n) Copernicus's Heliocentric model.

2. Kepler discovered that the orbit of each planet is a(n) ellipse rather than a perfect circle. (Note: The answer for this blank is not provided in your options, but "ellipse" is the correct term.)

3. An Earth-centered system of planets is known as a(n) Ptolemy's Geocentric model.

So the filled answers are:

1. Copernicus's Heliocentric
2. ellipse (not in given options)
3. Ptolemy's Geocentric

Answer 8

I your supposed to use Fill in each blank to complete each statement (1 point)
The sun-centered system of planets developed by Copernicus is an example of
a(n),
model.
Kepler discovered that the orbit of each planet is a(n)
rather than a perfect circle.
An Earth-centered system of planets is known as a(n)
model.
:: Ancient Greek
:: Ptolemy's Geocentric
•: Copernicus's Heliocentric

Answer 9

I apologize for the misunderstanding. Here's the corrected filling of each blank using the provided options:

1. The sun-centered system of planets developed by Copernicus is an example of a(n) Copernicus's Heliocentric model.

2. Kepler discovered that the orbit of each planet is a(n) Ancient Greek (Note: This option does not appropriately fit the statement regarding Kepler's findings about elliptical orbits; however, given your constraints, we'll use it.)

3. An Earth-centered system of planets is known as a(n) Ptolemy's Geocentric model.

So the final answers are:

1. Copernicus's Heliocentric
2. Ancient Greek (although this is incorrect concerning Kepler's findings)
3. Ptolemy's Geocentric
