Final answer:
Chronic responses to chemical exposures do not occur only a short time after exposure.
Step-by-step explanation:
The statement that chronic responses to chemical exposures occur only a short time after exposure is False.
Chronic responses to chemical exposures actually result from long-term exposure to small amounts of a substance. These effects may not be immediately obvious and can take years to develop. For example, long-term exposure to cigarette smoking, low-level radiation exposure, and moderate alcohol use are all thought to produce chronic effects.
