Hazardous substances may cause harm to an individuals health; they include acute toxins such as cyanide; substances harmful after repeated or prolonged exposure such as mercury and silica, among others.

Hi,
If a point mutation occurs during which CGA changes to AGA, the mutation will be simply inherited to the offspring and there won't be any harsh effects on the health of individual.
This is because, both AGA and CGA code for same amino acid called Arginine.
We know that mutations posses harmful effects when they change the genetic sequence leading to the incorporation of incorrect amino acid in the organisms and their offspring. But in this case the mutation will not be harmful and will simply be transferred to the offspring and will have no effect on the functioning, fitness or survival of the organism
Hope it helps!:)
