Suggest an explanation for the colors of Spiral, Elliptical, and Irregular galaxies. In particular, comment on the amount of gas and dust and the stellar populations of those galaxies.

Answers

Answer 1

A possible explanation for the different colors of the Spiral, Elliptical, and Irregular galaxies comes from the types of stars found in those galaxy regions.

What is a spiral galaxy?

The spiral galaxy has twisted collections of stars and gas that often have beautiful shapes and are made up of hot young stars.  For example, the Milky Way is a spiral galaxy with a rotating disc and spiral 'arms.'

The color of a spiral galaxy is much redder than the colors of irregular galaxies.

What is an elliptical galaxy?

An elliptical galaxy is a galaxy that has a generally elliptical shape, no apparent internal structure or spiral arms, with little dust and gas, and apparently a reduced population of stars.  The main color is red.

What is an Irregular galaxy?

Irregular galaxies lack shapes. They are small galaxies filled with a lot of hot gas and dust with blue colors. There is a large population of stars here.

Thus, spiral galaxies are the most common, followed by elliptical galaxies (though much older and invisible), but irregular galaxies have bulging stellar populations due to the presence of too much hot gas and dust.

7. La ? es buena ,escuelo,escuela,escuelas,escuelos

Answers

Answer:

The correct answer for this question would be escuela.

Explanation:

The first answer (es buena) is a phrase that translates to "is nice". The word "la" translates to "the", so the combined phrase would be "The is nice", which does not make sense.

The rest of the answers are translations for the words school and schools.

Anything that ends in an "o" is masculine, which means that it requires the masculine form of 'the' (lo for singular and los for plural). This means that the answers escuelo and escuelos are incorrect.

This leaves escuela and escuelas as possible answers.

Since the word "la" is singular, you need the singular version of school, which is escuela. The world "escuelas" translates to schools, and it would require the plural version of 'the' (las) for it to be the correct answer.

How did Galveston recover from the Great Storm?

Answers

Answer:

Galveston built a massive seawall to turn back storm-generated waves.

Explanation:

The Second Industrial Revolution was lucrative for the business owners of the Gilded Age. As titans of business like Cornelius Vanderbilt and JP Morgan amassed a fortune, residents of cities worked long hours in terrible working conditions for low wages. With the institution of mass production and assembly line business practices, factories grew rapidly. These factories were staffed not only by men and women, but also relied on child labor. Though opportunities for African Americans existed, factory work was still segregated. Labor unions were formed to fight back on behalf of workers, but many businesses were monopolies. With little competition, business owners had the power to set wages and working hours with no input from workers or unions. This left most workers poor and overloaded, living in crowded and unsanitary tenements around America’s largest cities. The divide between rich and poor grew in both wealth and distance. As elevated railroads and subway systems were built, the rich moved farther away to wealthy neighborhoods or suburbs and only came to the city center during working hours.

With which of the following statements would a labor union leader in the Gilded Age most likely agree?

A
Business owners built their business from the ground up, so they should have final say over worker pay.

B
Inequality is not an important issue. What really matters is building more subway systems.

C
It is the responsibility of a business owner to ensure the safety and fair treatment of their workers.

D
Tenements are dirty and crowded because workers do not take enough responsibility for their actions.

Both the ancient Mesopotamian and ancient Egyptian civilizations began in river valleys in dry climates. Both civilizations modified their environment in a number of ways. For example, they built canals and dams, which provided water for farming and saved their cities from flooding and drought. Both of these regions thrived for thousands of years. Think about how important it is for a government to provide a stable food supply, laws, and protection for a civilization to thrive. Based on what you’ve learned about ancient Mesopotamia and ancient Egypt, what kind of leadership does such a civilization need? What does a government need to do to protect the way of life for its people? Can you think of any instances when the government did not attend to the needs of the people?

Answers

Answer:

Decisive actions

Explanation:

The government of those people obviously had to have control over the population, like all countries today.

Do not think that governments back then were very different from our own. The governments we have now are based on the ones in the past.

The kind of leadership required is the one where the leaders listen to what is necessary to do for society. Not necessarily listen to the people, but to what needs to be done.

If there is a plague in one part of town, seal it and use lethal force to contain it.

Harsh but decisive and necessary actions.

The governments also had to keep up the army so that frequent foreign invaders could not ruin all your civilization has built.

Successful civilizations are the ones that managed to keep the people united and organized. Look at Egypt, Mesopotamia, the Roman Empire. They were all very organized and had achieved great economy.

Strength in numbers is an understatement.

The leader(s) can also not be short of actions. If there is a pressing matter that needs your immediate response, a weak leader is not appropriate. That's why dictatorships fall - the first leader is good at ruling, but his son might not have it in him.

The key is to keep the people organized and on the side of the government.

What groups of elites struggled for power in Latin America in the 1800s?

Answers

Answer:

While Brazil maintained its territorial integrity after independence, the former Spanish America split into more than a dozen separate countries, following the administrative divisions of the colonial system. The difficulty for the inhabitants of these units was not, however, as simple as the demarcation of geographic boundaries. Rather, the recently emancipated countries of Latin America faced the much more daunting challenge of defining and consolidating new nations. With the structures of the old system removed, the inhabitants of each country set out on programs to create a postcolonial political, economic, and social order. The obstacles confronting them were myriad and imposing. As Bolívar himself exclaimed in a final cry of despair, “America is ungovernable for us…; he who serves a revolution ploughs the sea.” Indeed, it was only toward 1850, at the end of a 25-year period sometimes known as “the long wait,” that the outlines of that new order began to take their definitive form across the region.
