They occur commonly in the Midwest.
Answer:
correct answer is option D (Red Pine distribution will shift northward into Canada)
Explanation:
Forest tree species are expected to endure significant population changes
in response to warmer temperatures across the United States.Red pine forests are negatively impacted by extreme summer heat, especially those
that have not been thinned. Red Pine species can be adapted to a wider range of climate, several subtropical and tropical pines, have a high degree of genetic variation and tolerate a wide range of climates. Performance in multi-site provenance trials shows that they are adapted well to a wide range of climates Thus they may also be able to adapt to new climatic conditions in their natural habitat.
Their are other factors which also influence red pine occurrence like soil conditions, plant competition. These factors are likely to be additional constraints for the present species distribution and future distribution shifts.
From these factors it is found that Red pine distribution will shift northward into Canada over the next 200 years.
Answer:
East and Southern Africa is the region most affected by HIV in the world and is home to the largest number of people living with HIV. The HIV epidemic in this region is generalized but young women, men who have intercourse with men, transgender people, intercourse workers, prisoners and people who inject drugs are at an increased vulnerability to infection. The number of people living with HIV in East and Southern Africa continues to increase, but access to antiretroviral treatment is increasing as well. Although laws and cultural traditions vary between East and Southern African countries, there are a number of ingrained cultural, structural and legal barriers to HIV prevention.
Explanation:
Igneous rocks are formed as magma solidifies on the earth surface.
The process that might have formed this rock is:
A. melting underground, violent volcanic eruption, and solidification above ground
<h3>Igneous Rocks</h3>
Igneous rocks are known to be rocks that are formed when the magma melts underground and rises up to the earth surface via volcanic eruptions.
When they rise to the earth surface, they cool and solidify. This process will then result to the production of crystals.
Intrusive and extrusive rocks are formed in this process.

The answer is "an American Colony".
"The ordinary man knows that [Saudi Arabia] is the largest oil producer in the world, yet at the same time he is suffering from taxes and bad services. Now the people understand the speeches of the ulemas in the mosques--that our country has become an American colony. They act decisively with every action to kick the Americans out of Saudi Arabia. What happened in Riyadh and [Dhahran] when 24 Americans were killed in two bombings is clear evidence of the huge anger of Saudi people against America. The Saudis now know their real enemy is America." - Osama Bin Laden, July 10th, 1996
