Question

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

Explanation:

Mutations can indeed alter protein synthesis as they change the DNA sequence which codes for proteins. Some mutations are harmful (e.g., causing genetic diseases like sickle - cell anemia), while others can be beneficial (e.g., providing resistance to diseases in some organisms). So, all the statements about mutations (altering protein production, being harmful, being beneficial) are correct.

Answer:

All of these are correct.
