What type of damage do mutagens cause to living organisms?

  1. Physical injury

  2. Chemical burns

  3. Genetic alterations

  4. Respiratory problems

The correct answer is: Genetic alterations

Mutagens are agents that can cause changes in the DNA of living organisms, leading to genetic alterations. These changes can manifest in various ways, including mutations that may affect cell function, protein synthesis, and overall genetic integrity. Genetic alterations can result in a wide range of consequences, from benign to harmful, depending on the specific changes made to the DNA sequence. The other types of damage mentioned do not accurately describe the effects of mutagens. Physical injury relates to damage to body structures or tissues and does not pertain to genetic changes. Chemical burns involve damage to skin or other tissues due to chemical exposure but do not imply any alterations to the DNA. Respiratory problems are typically associated with breathing difficulties or damage to the lungs, which again do not correlate with the direct effect of mutagens on genetic material. Therefore, the correct answer focuses on the unique and defining impact that mutagens have on the genetic integrity of organisms.
