Answer:
Megaloblastic anemia is most often due to hypovitaminosis, specifically vitamin B12 (cobalamin) and folate deficiencies, which are necessary for the synthesis of DNA. [3] Copper deficiency and adverse drug reactions (due to drug interference with DNA synthesis) are other well-known causes of megaloblastic anemia.

Answer:
The projections, if they play out, illustrate the potential magnitude of decisions such as the recent one by President Trump to walk away from the international Paris climate accord, in which more than 170 countries agreed to slash their carbon emissions in coming years. Meanwhile, hundreds of governors, mayors and other elected officials have vowed to continue the shift toward cleaner sources of energy.
Hsiang acknowledged that despite the researchers’ efforts to use sound statistical approaches and a wealth of databases, calculating the future costs of climate change is inherently uncertain. Communities are likely to adapt and become more resilient. Industries evolve and relocate.
Delavane Diaz, a senior technical leader at the Electric Power Research Institute, agreed that the study has limitations. For one, it fails to account for how humans will probably plan for and respond to the changing climate. Still, she said, the conclusions provide an important glimpse of the economic risks the United States could face as global warming worsens.

Answer:
Incomplete decomposition of organic matter due to a lack of oxygen. (Ans D).
Explanation:
Coal is known as the mostly carbon with containing different amounts of oxygen, nitrogen, sulfur, and hydrogen. Coal is formed when Incomplete decomposition of dead plant matter due to a lack of oxygen occurs. In-plant matter because of the pressure, and heat-generating physical, and chemical changes occur which lead to force out oxygen, and carbon deposits left. so, in this time the plant matters become coal.
Coal is divided into three main types which are based on the percentage of hydrocarbon, oxygen, and carbon occurs in the coal.
1) Anthracite coal.
2) Bituminous coal.
3) Lignite coal.
