Question

if a substance in the ocean bioaccumulates, then what other characteristic is it most likely to have?
a. high toxicity
b. high persistence
c. ability to biodegrade
d. ability to block sunlight

Explanation:

Bioaccumulation requires a substance to remain in the environment long enough to be taken up and stored in organisms. High persistence means the substance does not break down easily, allowing it to accumulate over time. While some bioaccumulative substances may be toxic, persistence is a more direct prerequisite. Biodegradability (C) would prevent accumulation, and blocking sunlight (D) is unrelated to bioaccumulation. Thus, high persistence is the most likely characteristic.

Answer:

B. high persistence
