Question

chronic toxicity is a measure of how poisonous a pesticide is after ______ exposure(s).
a. eight
b. twelve
c. a single
d. repeated

Explanation:

Chronic toxicity refers to the harmful effects of a substance (like a pesticide) that occur after repeated or long - term exposure. Acute toxicity is related to a single exposure. The options “eight” and “twelve” exposures are not the standard definitions for chronic toxicity. So the correct option is the one related to repeated exposure.

Answer:

d. repeated
