Answer:
The cells change after being exposed to the chemical, and this change is passed to the next generation of cells.
Explanation:
A mutation is any change, whether big or small, that occurs to the nucleotide sequence of a gene in a cell as caused by mistake during replication or induced by a mutation causing substance. These mutation-causing substances are called MUTAGEN.
A MUTAGEN is any substance that causes genetic mutation in an organism's cell. These changes in the nucleotide sequence can affect one or more phenotypic characteristics of the affected organism, which is also passed to offsprings because it is a genetic change.
Hence, a plant cell exposed to this mutagen will be induced to mutate.
Hence, the cells changing after being exposed to the chemical, which is also passed to the next generation of cells best provides explanation that the chemical is a MUTAGEN.
Answer: Because they have built up immunity from past medications.
Explanation: As people get sick and are given antibiotics the 99.9 % are removed but that one percent from the bacteria is able to overcome the antibiotics and make itself stronger and immune to the medicines, then the bacteria evolves and a new person will get infected and will need stronger antibiotics further more the cycle is repeated.
