Answers
The best set of changes that describe a native mountain dweller is B. Hematocrit - increases; Arterial O2 Content- decreases; Arterial PO2-decreases.
Hematocrit is the percentage of red blood cells in your blood as determined by volume. Blood is made up of plasma, which also contains white blood cells, platelets, and red blood cells. Together, they account up around 45% of the total volume of human blood, however the precise ratios of each component may vary. The arterial oxygen content is the sum of the oxygen dissolved in arterial blood and the oxygen bound to hemoglobin. How much dissolved oxygen gas is present in the blood is determined by the partial pressure of oxygen, or PO2. In essence, it evaluates how efficiently the lungs can transport oxygen into the blood.

What is the Nigerian government doing to help solve the contemporary issues in Nigeria?
Answers
Answer: The Nigerian government is trying to address various security, economic, social and political issues in the country, but faces many challenges and criticisms.
Explanation: Nigeria is a large and diverse country with a population of over 200 million people and more than 250 ethnic groups. It has a federal system of government with 36 states and a capital territory. It is also Africa’s largest economy and most populous democracy.
However, Nigeria also faces many contemporary issues that threaten its stability and development. Some of these issues are:
Jihadism: Nigeria has been fighting an insurgency by Islamist militant groups such as Boko Haram and the Islamic State’s West Africa Province (ISWAP) in the north-east of the country since 2009. These groups have killed thousands of people, displaced millions more, and disrupted education, health care and livelihoods. The Nigerian government has deployed military and police forces to combat the militants, but has struggled to contain their attacks and prevent their expansion into other regions. The government has also faced accusations of human rights violations and corruption in its counter-terrorism efforts.Clashes between herders and farmers: Nigeria has also witnessed violent conflicts between nomadic cattle herders and sedentary crop farmers over land, water and grazing rights. These conflicts have been worsened by climate change, population growth, environmental degradation and ethnic tensions. The clashes have resulted in hundreds of deaths, injuries, displacement and destruction of property every year. The government has tried to mediate between the parties, establish peace committees, enforce laws and regulations, and provide alternative grazing reserves for the herders, but these measures have not been effective or widely accepted.Economic downturn: Nigeria’s economy has been hit hard by the COVID-19 pandemic, low oil prices, insecurity, inflation and unemployment. The country entered its second recession in five years in 2020, with a contraction of 1.8% in its gross domestic product (GDP). The poverty rate is estimated at 40%, while the youth unemployment rate is at 32.5%. The government has introduced various stimulus packages, social protection programs, infrastructure projects and reforms to boost the economy and cushion the impact of the crisis on the people, but these have been insufficient or delayed by bureaucratic bottlenecks and corruption.Social issues: Nigeria also faces various social issues such as poor health care, education, gender inequality, child mortality, human trafficking, drug abuse and environmental pollution. These issues affect the quality of life, human rights and well-being of millions of Nigerians. The government has enacted policies and laws to address these issues, such as the National Health Act, the Universal Basic Education Act, the Violence Against Persons Prohibition Act and the National Drug Control Master Plan, but their implementation and enforcement have been hampered by lack of funding, capacity, coordination and political will.Political issues: Nigeria’s political system is characterized by weak institutions, poor governance, corruption, electoral violence, godfatherism, tribalism and media censorship. These issues undermine the legitimacy, accountability and responsiveness of the government to the people’s needs and aspirations. The government has faced protests and criticisms from various civil society groups, opposition parties, religious leaders and international partners over its handling of the security, economic, social and political challenges in the country. The government has also been accused of violating human rights, suppressing dissenting voices and shrinking civic space.These are some of the major contemporary issues in Nigeria that the government is trying to help solve. However, it is clear that the government alone cannot solve these problems without the support and participation of other stakeholders such as state governments, local communities, civil society organizations, private sector actors and international partners. There is also a need for more dialogue, collaboration and trust-building among these actors to address the root causes and drivers of these issues.

B) Star X is 100 times brighter than star Y.
C) Star Y is 5 times brighter than star X.
D) Star Y is 100 times brighter than star X.
Answers
Star X has an apparent magnitude of 3, and star Y has an apparent magnitude of 8. They compare in observed brightness: C) Star Y is 5 times brighter than star X.
The apparent magnitude of a star is a measure of how bright it appears from Earth. The lower the apparent magnitude, the brighter the star appears. Star X has an apparent magnitude of 3, and star Y has an apparent magnitude of 8.
The apparent magnitude scale is a logarithmic scale used to measure the brightness of celestial objects as observed from Earth. In this scale, lower numbers represent brighter objects.
The difference in apparent magnitude between two stars can be used to determine their relative brightness. The formula to calculate the brightness ratio between two stars based on their apparent magnitudes is: Brightness ratio = 2.512^(m2 - m1)
Therefore, Star X appears brighter than Star Y: C) Star Y is 5 times brighter than star X.

1. what are the two basic features of a fault and how would you differentiate between them?
Answers
The two basic features of a fault are hanging and footwall. The hanging wall is the upper side of the fault plane while the footwall is the lower side of the fault plane. The hanging wall moves downward and the footwall moves upward. The surface of the Earth is covered by a network of large cracks known as faults.
The earth's crust is in motion, which causes pressure to accumulate on the rocks, and this leads to the development of cracks that may result in earthquakes. Faults occur when rocks are subjected to a lot of pressure and break, forming a fracture or crack that separates the rocks. A fault occurs when two large blocks of the earth's crust shift position relative to one another. The movement of the rocks, as well as the direction in which they move, determine the type of fault. There are two types of faults based on their motion, namely, normal faults and reverse faults. A normal fault is characterized by the hanging wall moving downward relative to the footwall. The hanging wall is the block of rock that lies above the fault plane, while the footwall is the block of rock that lies below the fault plane. When the stress that created the fault is greater than the friction holding the rocks together, the rocks break apart, causing the hanging wall to move downward relative to the footwall.
On the other hand, reverse faults occur when the hanging wall moves upward relative to the footwall. Reverse faults are also called thrust faults, and they occur when rocks are under compression, and the hanging wall moves up. The hanging wall is usually moved up over the footwall. The reverse fault has an angle that is steeper than 45°.
In conclusion, the two basic features of a fault are hanging and footwall. The hanging wall is the upper side of the fault plane while the footwall is the lower side of the fault plane. The hanging wall moves downward and the footwall moves upward. Faults occur when rocks are subjected to a lot of pressure and break, forming a fracture or crack that separates the rocks.

What was the effect of the New Deal on labor?
Collective bargaining was prohibited.
Union membership declined during the New Deal.
(Unions benefited from government support.) it’s this one lol
Answers
The New Deal had a significant effect on labor, particularly with regards to unions and collective bargaining prohibited.
One of the primary goals of the New Deal was to provide support for workers and improve their working conditions. This was achieved through various legislation and policies enacted under President Franklin D. Roosevelt's administration.Unions greatly benefited from the government support provided by the New Deal.
The National Industrial Recovery Act (NIRA) of 1933, for example, granted workers the right to organize and bargain collectively with their employers. This was a crucial step in establishing the foundation for modern labor relations in the United States.Additionally, the Wagner Act, also known as the National Labor Relations Act (NLRA) of 1935, further solidified the rights of workers to form and join unions.
This act also established the National Labor Relations Board (NLRB), an independent federal agency tasked with enforcing labor laws and ensuring fair labor practices.Contrary to the notion that union membership declined during the New Deal, the support provided by these policies actually led to a significant increase in union membership. Workers gained more bargaining power, and employers were legally obligated to negotiate with unions in good faith.

a. formation of the Circumpolar Current
b. decrease in worlds overall climate
c. Messinian crisis
d. position of continent on the pole
Answers
The answer to the question is c. Messinian crisis.
The Messinian crisis occurred during the late Miocene epoch, approximately 5.96 to 5.33 million years ago, and involved a significant reduction in the Mediterranean Sea's water levels. While this event did have an impact on the global climate, it did not directly cause the glaciation of Antarctica. The formation of the Circumpolar Current, which isolated Antarctica from warmer ocean currents, played a crucial role in the continent's glaciation. Additionally, the continent's position on the pole and the decrease in the world's overall climate also contributed to its glaciation. These factors created a feedback loop in which ice sheets formed, which then reflected more sunlight, causing temperatures to drop further and the ice sheets to expand. Overall, it was a combination of several factors that led to the glaciation of Antarctica, with the Messinian crisis not being one of them.
