Question

how do mutations affect living things? mutations alter the way proteins are made. mutations cause changes that are harmful to living things. all of these are correct. mutations cause changes that are beneficial to living things.

Explanation:

Mutations can alter the genetic code. Since genes code for proteins, mutations can change how proteins are made. Mutations can be harmful (e.g., causing genetic diseases like sickle - cell anemia), beneficial (e.g., antibiotic resistance in bacteria, which helps them survive in an antibiotic - rich environment), or neutral. So, the statement that "Mutations alter the way proteins are made" is correct. Also, mutations can cause both harmful and beneficial changes.

Answer:

Mutations alter the way proteins are made.
