Answer:
the answer is D.because the D represent cotyledon and at the same time the leaves which stores food during photosynthesis.
Answer:
B. local water contamination
D. destruction of ecosystems
Explanation:
The mining, be it a surface one or underground one, has several negative impacts on the surrounding area. Two common negative impacts of both types of mining are contamination of the local waters, as well as the destruction of ecosystems.
The waters get heavily polluted with toxic chemicals pretty much always ad everywhere where there is mining. The main reason for this is that the nus-products from the mining are released into the waters. This causes high level pollution of the waters, thus making it not good for anything, and the aquatic life in the waters dies out rapidly.
The fact that the waters are heavily polluted means that everything that comes in touch with them becomes heavily polluted as well. Also, apart from releasing chemicals in the waters, the mining requires space, so the area is cleared out, and after that lot of toxic material is disposed on it. The majority of the plants can sustain that, so they die out, and since they are the basis of the ecosystems, the animals die out as well.
The water would keep the magma at the same temperature restricting it from getting hotter keeping the temperature at melting point but not enough to turn into a flowing liquid
Answer:
The natural resources of the Arctic are the mineral and animal resources within the Arctic Circle that can provide utility or economic benefit to humans. The mineral resources include major reserves of oil and natural gas, large quantities of minerals including iron ore, copper, nickle, zinc phosphates and diamonds.
Explanation:
The Arctic resources race refers to the competition between global entities for newly available natural resources of the Arctic. Under the United Nations Convention of the Law of the Sea, five nations have the legal right to exploit the Arctic’s natural resources within their exclusive economic zones: Canada, Russia, Denmark, Norway, and the United States (though the U.S. has yet to ratify the treaty, it considers the treaty to be customary international law and abides by it).
The Arctic region and its resources have recently been at the center of controversy and pose potential conflicts between nations that have differing opinions of how to manage the area, including conflicting territorial claims. In addition, the Arctic region is home to an estimated 400,000 indigenous people. If the ice continues to melt at the current rate, then these indigenous people are at risk of being displaced. The acceleration of ice depletion will contribute to climate change as a whole: melting ice releases methane, ice reflects incoming solar radiation, and without it will cause the ocean to absorb more radiation (albedo effect), heating up the water causing more ocean acidification, and melting ice will cause a rise in sea level.
