Answer:

Presence of gravitational collapses and ripples, electromagnetic radiation.

Explanation:

The existence of black holes in our galaxy, including a supermassive black hole at the center of the Milky Way, is highly likely based on astronomical observations and measurements of stars' orbits around a massive, invisible object.

The likelihood that black holes exist in our galaxy is extremely high. Observations conducted by various astronomical teams, using powerful telescopes like the Hubble Space Telescope and ground-based observatories, have provided compelling evidence of a supermassive black hole at the center of the Milky Way. This evidence comes from tracking the orbits of stars near the galactic center, indicating they are gravitating around a massive, invisible object with a mass estimated at approximately 4 million solar masses. This region, despite its massive gravity, emits no light that we can directly see, suggesting the presence of a black hole with properties consistent with those predicted by physics.

Moreover, researchers have found that most galaxies harbor black holes at their centers, indicating that black holes are a common component of galactic structure. The correlation between a black hole's mass and its host galaxy's properties suggests a significant relationship between the growth of black holes and their galaxies. Not only are supermassive black holes found at the centers of galaxies, but recent X-ray observations also suggest the existence of intermediate-mass black holes within crowded regions of space, like globular clusters.

The black hole located at the core of the Milky Way is referred to as a supermassive black hole because it contains a mass equivalent to millions of suns. Its existence is affirmed by the behavior of stars orbiting an invisible object and by the lack of any other plausible explanation for the observed gravitational effects. While we cannot see them directly due to light absorption by interstellar dust and their nature of not emitting light, black holes can nonetheless be detected through their immense gravitational influence on nearby objects.

D.gender inequality

Explanation:

    Gender inequality is a social and cultural phenomenon where gender discrimination occurs, primarily between men and women. Moreover, it is not an innocuous phenomenon, as its impact can be noticed in different planes: labor, social, family, etc.

    At the social level, for example, a woman may appear subordinate to her husband or father. At the economic level, women continue to receive lower wages than men in the same job (wage gap). Housekeeping or childcare are still seen as tasks linked to women rather than men. So we could go on completing a long list.

    Faced with it, feminism or the gender perspective allows us to look at the world from another point of view. However, changing our perspective can cause discomfort or discomfort. That is why the purpose of these lines is to sharpen our eyes so that we can relate to the world in a fairer way.

The Challenger did not perform deep sea trawling; other methods such as bottom sampling, water analysis, and sonar soundings were likely part of its experiments.

The Challenger experiments involved numerous scientific studies related to marine biology and oceanography, but based on the context provided, it seems that deep sea trawling was not one of the experiments performed during its missions. The Challenger's research might have covered aspects like bottom sampling, water analysis, and sonar soundings to understand the marine ecosystem better. These methods are routinely used to explore aquatic environments without causing significant harm to the habitat, as well as studying the spread of species via ballast water, the biology of deep-sea organisms, and the chemical properties of different environments, such as the soils on Mars.

A savanna is more likely to be found in a dry climate. In this case, the answer is tropical climate.

The correct answer is - tropical climate.

The savanna is a vast grassland where the trees and shrubs are relatively rare. It is a semi-arid region. For most of the year, the savanna is dominated by the yellowish color because it is dry, and only in one short period of the year it gets rain, a large amount of it, but it is for the whole year, and in this period it shortly turns to a green grassland.

It is located in close proximity to the Equator, and it is part of the group of the tropical climates. The biggest portion of the savanna's can be found on the soil of Africa, lying between the tropical rainforests and the deserts.

Those who reside in sub-Saharan Africa are mostly Bantu speakers. These cultural groupings share comparable traditions, and there are few linguistic differences between them.

There are about 400 different ethnic groups that make up the Bantu people, sometimes known as the Bantu, and they all speak Bantu languages. They originate from 24 different nations that cover a huge territory extending from Central Africa to Southeast Africa and Southern Africa.

The number of Bantu languages is in the hundreds. Between 440 and 680 different languages are thought to exist, depending on how you define a "language" or "dialect." The total number of speakers is in the hundreds of millions, with an estimate of 350 million in the middle of the decade (or around 30% of Africa's population or about 5% of the world's population).

There are about 200 ethnic or tribal groupings and about 60 million speakers in the Democratic Republic of the Congo alone as of 2015.

Answer:

b) Gulf Stream winds

Explanation:

The Gulf Stream wind is a powerful ocean current that joins the Atlantic Ocean with warm water from the Gulf of Mexico. This reaches all the way up the United States to Canada's eastern coast. A large system of circular currents and strong winds called an oceanic gyre, causes the Gulf Stream. Earth has five oceanic gyres. The Gulf Stream is part of the Subtropical Gyre in the North Atlantic.

Final answer:

The subsidence of the ground beneath the Nelson's house, causing it to sag and sink, can be due to the exhaustion of groundwater, as seen in the case of Venice or through the collapse of limestone caverns, demonstrated by the Guatemala City sinkhole event.

Explanation:

The ground beneath the Nelson's house is beginning to sag and sink. A possible explanation for this phenomenon can be attributed to subsidence caused by the exhaustion of groundwater. When groundwater is removed, the soil can begin to compact due to the loss of buoyant support that the water provides, leading to subsidence.

This is highlighted in places like Venice, where the pumping of groundwater coupled with the overlying weight of structures has caused the city to sink. Moreover, subsidence can also occur in a more dramatic form known as fast subsidence, where the lowering of the water table below the level of underground caverns, primarily in limestone regions, leads to their collapse and the formation of sinkholes. This is exemplified by the massive sinkhole that appeared in Guatemala City in 2007.

During volcanic eruptions, the pieces of rock and debris propelled through the air are known as tephra and ash. Tephra includes larger particles, while ash comprises finer fragments that can travel long distances and cause a variety of issues.

The pieces of rock and debris that are carried within lava and propelled through the air during an eruption are known as tephra and ash. Tephra refers to the ejected rock materials of various sizes, where the larger blocks, known as bombs, can pose significant hazards due to their size and proximity to the vent. Ash, on the other hand, consists of much finer fragments, less than 2mm in diameter, and can be carried long distances away from the vent, causing issues such as building collapses and respiratory problems. Hot ash can also disrupt services like airline transportation far from the eruption site, as demonstrated in the disruption caused by the Eyjafjallajökull volcano in 2010, which resulted in a significant air travel disruption in northern Europe. Both tephra and ash are critical in understanding the hazards posed by volcanic eruptions.

b. Ireland

Explanation:

b. Kells was located on the mainland of Ireland.

The correct answer is Ireland. Kells is a town in County Meath, Ireland, and is historically significant for its association with the Book of Kells, an illuminated manuscript created by the monks around the 9th century. The Book of Kells is often associated with both Iona in Scotland and Kells in Ireland due to the movement of monks between these locations after a Viking raid in 806.

Answer:

C. Pizza originated in Italy, but was brought to the United States in the 1800s by Italian immigrants.

Explanation:

    The history of pizza mentioned above is only possible because of a process called immigration.

   Immigration is the act of entering or staying in a country other than one's origin, whether for the purpose of tourism, work or study. The term “immigration” is used from the point of view of the immigrant's destination country, ie the recipient.

   With the same concept, airport immigration also refers to people coming from countries other than the local country. It is in immigration that visitors answer some questions about their stay at the place of destination and whether or not they are allowed to enter the country. Thus, upon receiving permission, they must follow the immigration laws there.

Intrusive igneous rock usually have larger crystals than extrusive igneous rock because b. because the magma cools much slower.

There are two types of igneous rock:

The slow cooling time of the intrusive igneous rocks ensures that the crystals they form are much larger than those formed by the extrusive rocks which cooled too fast.

In conclusion, the magma cooling much slower under the surface leads to intrusive igneous rocks having large crystals.

Answer:

False

Explanation:

Geneva is in the French-speaking part of Switzerland. (hence "Genève") and Geneva is the capital of the Swiss Canton of Geneva, located in the south-westernmost corner of Switzerland. The city is situated along the banks of Europe's largest lake, Lake Geneva (Lac Léman), at the mouth of the Rhone River and is bordered by the Jura Mountains to the west and the French Alps in the east. So it's false.
