Acute toxicity occurs after: Repeated and/or prolonged exposures Single or short exposures Following exposure to a hazardous chemical Exactly 3 exposures

Multiple Select QuestionSelect all that applyWhich of the following statements about chronic and acute exposure and effects are correct?Multiple select question.Chronic exposures are rarely life-threatening because the dosage in each exposure is generally very small.Acute exposures, because they involve short contact with a toxic chemical, rarely have long-term effects.Acute exposure involves a single contact with a toxic chemical. It may last a few seconds or a few hours.Chronic exposure involves continuous or repeated contact with a toxic substance over a long period of time (months or years).Need help?

The variety of responses among organisms that get the same dose of chemical is due to----Question 25Answera.A+Cb.Extent of exposurec.Dosed.individual susceptibility

What does the saying "the dose makes the poison" mean?Multiple choice question.All substances have equivalent potential for harm, so exposure to any of them is risky.Any amount of a dangerous substance is unacceptable and counting the numbers of compounds detected is a reliable way to establish danger.Most substances are toxic at some level of exposure depending on the substance and the nature of the exposure.What matters is the amount of a toxic substance present; whether or not we are exposed to the toxin is not relevant.Need help?
