1. Mutation is any alteration or change in the nucleotide sequence of the genetic material of an organism.
2. Middle ear infections affect the space behind the eardrum. That air-filled space contains small, vibrating bones that allow to hear. It is connected to the throat by a pair of narrow tubes called Eustachian tubes
