Explain how inhaling increased amounts of CO2 affects pulmonary ventilation. Humans cannot survive for more than a few minutes without O2. Why? Why might neurotoxins be helpful to humans? Why is methane the worst greenhouse gas? Is it just because its a huge molecule? Why does smoking or inh...

HumansLaboratory animalsDosageNumerous patrol studies have provided a sizable data base of levels of CO2 exposure and health problems encountered by Naval nuclear submariners. Humans have been exposed to a variety of concentrations of CO2 for chronic periods of time aboard submarines, as well as in...
for both humans as well as animals. As a result, the rotation from soil to humans thru plants and back into the soil following the expiry of upper consumers provides a pathway for HMs to persist in the environment for extended time periods, causing a variety of negative impacts. Ingestion ...
For about twenty years it has been clear that the metabolic problems that cause calcium to be lost from bones cause calcium to increase in the soft tissues, such as blood vessels. The role of phosphate in forming calcium phosphate crystals had until recently been assumed to be passive, but ...

Plastics were considered as a magical material owing to their strong, non-degradable and versatile characteristics. After five decades of mass application, plastics’ property of non-biodegradability has become one of the key concerns for scientists, civ
The answer is ... (thanks to Mark Cramer, Tampa) ... It depends - on whether the sources of indoor pollutants - (excluding roadway NOX) that are likely to be present - fuel burning appliances, are likely to produce hazardous levels of NOx *without* producing detectable levels of CO2 or...

All of the three members utilize non- carbohydrate sources of carbon for growth (see below). The genus Methylophaga belonging to the γ-subclass of Proteobacteria is a unique methylotrophic group, which consumes one-carbon (C1) compounds of a more reduced form than that of CO2 as a sole ...
