Multiple choice

What is the term used to describe the accumulation of toxic substances in the body over time?

  1. Biomagnification

  2. Bioaccumulation

  3. Biodegradation

  4. Bioremediation
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Bioaccumulation refers to the process by which toxic substances accumulate in the body of an organism over time. These substances can enter the body through various pathways, such as ingestion, inhalation, or skin contact. As the organism continues to accumulate these toxins, they can reach harmful levels and pose a threat to the organism's health.
