The effect of such toxic chemicals to the body is that they stimulate uncontrolled cell division. Uncontrolled cell division or cells proliferation may lead to cancer. The unchecked cell growth results to mutations in genes that can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death.

Explanation:
Given the baltimore's scheme which used for virus classifications, the most closely related option of virus to the described polio virus with a single stranded RNA in the question would be retroviruses that require a DNA intermediate.
Because much like the single-stranded RNA viruses, the retroviruses do not contain any DNA but they do have an enzyme named reverse transcriptase which they can use to replicate their RNA into the host cells DNA and use the end product for their benefits. So they both work in similar ways.
I hope this answer helps.

Answer:
Phenotypic plasticity in yeast cells is beneficial because this allows the yeast to change its phenotype of being a male or female. This plasticity depends on the type of pheromone exposure. The ability to change phenotype increases the reproductive success of yeast cells. This condition is useful for yeast, especially if they must adapt to changes affecting their reproduction and survival. By having phenotypic plasticity, the yeast can continue to grow its population size.
