Programmed cell death, or apoptosis, is an essential part of animal development. In the nematode, with its invariant cell lineage, particular cell lineages or particular cells within specific lineages are destined to end in programmed cell death, and it was this feature that allowed the identification of the process and the analysis of its genetic control.

A new chemical pesticide developed for agricultural use was subjected to the Ames test. The rate of mutation seen in samples treated with the pesticide and liver extract was approximately half that of the samples treated with the liver extract alone; in samples treated with only pesticide, the mutation rate was about the same as that of untreated samples. Which of the following statements could you make about this pesticide?
