What can we infer from the first paragraph? A. A lot of seas will become dead seas. B. It's hard for fishermen to make a living. C. Millions of people will leave coast regions. D. Ocean zones with zero oxygen increase faster.( )2. Which is the direct reason that results in the...
Increased volcanic activity could also exacerbate global warming. Eruptions rich in carbon dioxide, a greenhouse gas, could contribute to climate change, outlasting the sulphur aerosols that can cause initial periods of cooling. Volcanoes now known to sit under the West Antarctic Ice Sheet could help...
Increased secretion of hydrogen ions would result in a ___ of blood ___? Blood: Blood is the body fluid composed of plasma and cells. It circulates gases and nutrients to cells and tissues. Blood contains almost 55% of plasma. Plasma is mainly made up of water (92%) but al...
The debate is complicated by the fact that increased nitrogen availability caused by nitrogen deposition has coincided with increasing atmospheric carbon dioxide concentrations. The latter could further stimulate primary production but also result in increased allocation of carbon to root exudates, which ...

Afforestation and reforestation projects in the karst regions of southwest China aim to combat desertification and improve the ecological environment. However, it remains unclear at what scale conservation efforts have impacted on carbon stocks and if vegetation regrowth occurs at a large spatial scale ...

The role of soil organic carbon in global carbon cycles is receiving increasing attention both as a potentially large and uncertain source of CO2 emissions in response to predicted global temperature rises, and as a natural sink for carbon able to reduce atmospheric CO2. There is general agreement...
