which of the following statements about mutations are accurate? select all that apply. mutations cannot result from interactions with the environment. some mutations are beneficial. some mutations are harmful. mutations can result from errors in dna replication.

Explanation:

• Environmental factors like UV radiation or chemicals can cause mutations, so the first statement is false.
• Mutations can be beneficial (e.g., antibiotic resistance in bacteria that helps survival), so this statement is true.
• Many mutations are harmful, such as those that cause genetic disorders like cystic fibrosis, so this statement is true.
• DNA polymerase can make mistakes during replication that lead to mutations if not repaired, so this statement is true.

Answer:

• Some mutations are beneficial.
• Some mutations are harmful.
• Mutations can result from errors in DNA replication.
