a scientist thinks that a certain chemical is a mutagen. she exposes plant cells to a large amount of this chemical in the laboratory.\nwhich statement best provides evidence that the substance is a mutagen?\nthe cells die within hours of being exposed to the chemical.\nthe cells grow more quickly than those that were not exposed to the chemical.\nthe cells change after being exposed to the chemical, and this change is passed to the next generation of cells.\nthe cells continue to divide at the same rate as before they were exposed to the chemical.

Answer

Brief Explanations:

A mutagen is a substance that causes changes in the DNA of an organism. These changes (mutations) can be passed on to the next - generation of cells. Cell death, increased growth rate, or unchanged division rate do not directly indicate mutagenic activity. Only when the cells change and this change is heritable does it suggest mutagenic action.

Answer:

The cells change after being exposed to the chemical, and this change is passed to the next generation of cells.
