the answer is a it can be used as an energy source by organisms
If
you check the barometric pressure and find that [sic] it is reading
only 920 millibars ... two effects possibly responsible for this lower
than average reading are 1) elevation (~2500' MSL) or 2) a LOW
pressure weather system such as a mid-latitude or tropical cyclone. Also <span>A storm is approaching or barometer is read over a mountain</span>
The options are all related, and the answer is D) All of the Above.
The synergistic effects of exposure to multiple toxins are more difficult to quantify and study. As a result, there is not sufficient research on how much a system can take when exposed to multiple pollutants. This lack of research also means that we often do not even know what the effect of these interactions between multiple toxins are.
As a result of these gaps in our knowledge of the interactions between toxins, it is difficult to evaluate the threshold for pollutants, since a system will rarely feature only one pollutant in isolation.
