LIFE SCIENCE

Detailed explanation-1: -They are calledbeneficial mutations. They lead to new versions of proteins that help organisms adapt to changes in their environment. Beneficial mutations are essential for evolution to occur. They increase an organism’s changes of surviving or reproducing, so they are likely to become more common over time.

Detailed explanation-2: -Most mutations are neutral, which means it has little effect on the organism. Some mutations are harmful when they decrease the fitness of an individual. However, if the mutation gives the individual an advantage on survival and reproduction, it is considered beneficial. Therefore, the answer is C.

Detailed explanation-3: -How can Mutations be Beneficial? Mutations can be beneficial for life and science. For example, mutations in the genetic sequence of bacteria have created new strains (variations) of antibiotic resistant bacteria. These variant strains are resistant to antibiotic drugs.

Detailed explanation-4: -Some mutations are beneficial and improve fitness. An example is a mutation that confers antibiotic resistance in bacteria. Other mutations are harmful and decrease fitness, such as the mutations that cause genetic disorders or cancers .
