Which statement best describes biomarkers of effect?

Explanation:
Biomarkers of effect measure changes in a biological system that indicate a response to exposure, often representing early adverse changes before symptoms or disease appear. They show that the body has responded to a chemical, helping link exposure to potential health outcomes. For example, elevated liver enzymes in blood signal hepatocellular injury from a toxicant. This differs from biomarkers of exposure, which reflect the amount of chemical or its metabolites inside the body, not whether a biological effect has occurred.
