2. D 细节理解题.根基第二段"McDonough, founder of William McDonough + Partners, is a world-famous architect, designer and urban planner. His latest point is that people should change the opinion about carbon. "It is we who have made carbon toxic(有毒的), " he writes. "In the right ...
Professor:It is poisonous to humans.Uh.actually, we used to think that it was toxic to all biological life, that it didn't serve any biological purpose.But new study suggests that cadmium can actually substitute for zinc, that organisms can use it instead of zinc when there isn't enough ...
Environmental studies conducted worldwide, including the Canary Islands, have consistently identified volcanic eruptions as significant contributors of inorganic elements known to be toxic to humans, such as Se, Cd, Pb and Hg [37, 38]. Notably, recent findings from the ISVOLCAN study have ...
Acceptable fire suppression methods are carbon dioxide, water spray and dry chemical extinguishers. When burned, it emits high levels of carbon monoxide, a poisonous, colorless, odorless gas, as well as hydrogen sulfide, which also is a toxic material. Once considered relatively harmless, carbonyl ...
Why is carbon dioxide more soluble than oxygen? Dipoles: Dipoles are formed when a covalent bond contains atoms with significantly different electronegativities. This results in a greater electron density around the more electronegative element, resulting in a partial negative charge on that element an...

Polluted air and steadily rising temperatures are linked to health effects ranging from increased heart attacks and strokes to the spread of infectious diseases and psychological trauma.
Some sources claim that alcohol is converted into sugar by the liver. This is not true. Alcohol is converted to a number of intermediate substances (none of which is sugar), until it is eventually broken down to carbon dioxide and water. Because too much alcohol is quite harmful to your ...
Neumann MA, Laster MJ, Weiskopf RB, Gong DH, Dudziak R, Forster H, Eger EI: The elimination of sodium and potassium hydroxides from desiccated soda lime diminishes degradation of desflurane to carbon monoxide and sevoflurane to compound A but does not compromise carbon dioxide absorption. Anesth...
Given the absence of approved treatments for pathogenic variants in Peripherin-2 (PRPH2), it is imperative to identify a universally effective therapeutic target for PRPH2 pathogenic variants. To test the hypothesis that formation of the elongated discs
