To test the effect of a gene on the ability of a plant to store environmental toxins, your lab sets up an experiment. You have a control group of young plants that have a mutation such that the gene in question can no longer function. The experimental group is a group of mature plants that have a fully active version of the gene. Variables such as temperature, humidity, light, etc. are the same for both groups. What can be said about this experimental design?
