Main Factors that Affect Clinical Consequence of Toxicity

... the toxicity process.The route of exposure can affect absorption, translocation, and perhaps metabolic pathways. Exposure of a toxicant to periods of stress and food intake may also be a factor. After ingestion of some toxicants, emesis may occur if the stomach is empty, but if partly filled, ...

Re: Help with indentifying object - can't narrow to even kingdom

... at the same time. This makes slime molds ideal tools for scientists studying mitosis, the process of nuclear division. Occasionally, during rainy periods, large plasmodia (up to a few meters in diameter) crawl out of the woods and into people's lawns and gardens. The plasmodium may be ugly to ...
