The answer to this is B, mutation.
mutation causes the genes or chromosomes to change permanently and these changes can be inherited to the future generations.
Those mistakes that cause mutations to occur may be either the faulty DNA replication or faulty separation of chromosomes during cell divisions.
Mutation may actually be beneficial, but it is rare. Some mutation does not bring any changes but many bring problems. One common result brought by mutation is Down's syndrome. This is because the 21st chromosomes failed to separate during meiosis.
So there you have it, the answer is B, mutation.

Answer:
1. The force applied to the ball by the pitcher will impact your ability to hit a home run because according to Newton's laws, the force that the ball hits the bat with will have an equal and opposite reaction, meaning the ball would be bounced off with the same amount of force as the pitcher applied to the ball.
2. It would be easier to hit a home run with a lighter ball because the lighter ball would not need as much force applied to it as a heavier ball would, and according to Newton's second law, F=ma, if the mass is less then it would affect the force in a negative way.
This is my work, so build on it, and do not copy it.
