Even though it is highly unlikely that she will develop breast cancer, there is still a very small chance that it can occur.
Well, this would be a science question, not a health question. But an example of the transfer of energy from the atmosphere to the lithosphere would be the water cycle which transfers the water mass energy from the atmosphere to the lithosphere and back again.
Answer: Natural Errors
Explanation: Mutagens can erase parts of DNA that then replicate, but is not a mistake made in copying DNA so that's not it. UV Radiation distorts DNA, but is not necessarily a mistake made in copying it. Natural Errors are mutations made by cells when they copy base pairs and ineffectively or for some other reason mutate/do not create the correct DNA, and the failure of cells to correct this is a mutation. This is also known as an error in DNA replication
