Answer:
e. Some individuals acquired triazine resistance during their lifetimes, and were able to pass it on to offspring
Explanation:
The term resistance in the exposed example refers to an inheritable change in the weed population sensitivity, which is reflected in the consecutive failure of the chemical effects on the herb population.
Herbicide might produce a genetic modification in the weed, leading individuals to survive under the effects of the chemical. The plants evolve with the capability of tolerating the chemical dose that is usually used to destroy a normal population of plagues.
Resistance to the toxic is associated with mutations in some of the genes.
A mutation is a change in DNI sequences that introduce new variants. Many of these are eliminated, but some of them might succeed and be incorporated into each individual. These mutations are the ones that have been selected by natural selection.
- The selective pressure or modeling environmental factor is the triazine herbicide
- The weed´s response to herbicide is the survival of only those that carry mutations.
- Natural selection benefits these mutations.
- The mutated herbs survive, become more resistant, and pass the mutation to their offspring.
