Why is it difficult to calculate the biological half-life of a compound with ongoing exposure?

Because the compound is continuously being metabolized
Due to fluctuations in the body's metabolic rate
Because it's hard to measure the exact amount of exposure
Exposure continues to add the substance to the body

The correct answer is: Exposure continues to add the substance to the body

It is difficult to calculate the biological half-life of a compound with ongoing exposure because, as exposure to the compound continues, the substance is continuously being added to the body. Therefore, it becomes challenging to measure the exact amount of the compound in the body and accurately determine its half-life. The other options, such as fluctuations in the body's metabolic rate or difficulty in measuring exposure, do not directly affect the calculation of the biological half-life and are not as critical as the continuous addition of the substance to the body.
