Answers (1)


Environmental factors can indeed be a source of genetic mutations. Mutations can be caused by exposure to various environmental factors such as radiation, chemicals, toxins, pollutants, and certain infectious agents. These factors can directly damage the DNA or induce changes in the DNA replication process, leading to mutations. Acquired behaviors, parental education, and physical exercise do not directly cause genetic mutations. While behaviors and environmental factors can indirectly influence genetic health (e.g., through lifestyle choices and exposure to certain substances), mutations themselves occur at the genetic level due to changes in the DNA sequence.

Option 1 is the correct answer.
