4 Farmers spray pesticides on their plants to protect the plants from being eaten by insects. Some individual insects have a genetic mutation that makes them resistant to the toxins in the pesticides. Which statement best describes how only a few resistant individuals resulted in the pesticide becoming ineffective? F The resistant insects change the toxin on the plants, making it safe for others. G The resistant insects grow larger and eat less of the plants. H The resistant insects eat the contaminated surface and leave the rest for others. J The resistant insects are able to survive to reproduce and create a population that is also resistant.

## Step 1The problem is about the concept of natural selection and genetic mutation. The farmers are using pesticides to protect their plants from insects. However, some insects have a genetic mutation that makes them resistant to the toxins in the pesticides.## Step 2The question asks us to identify the statement that best describes how the pesticide becomes ineffective due to the presence of these resistant insects.## Step 3Looking at the options, we can see that option J is the most accurate. It states that the resistant insects are able to survive and reproduce, creating a population that is also resistant. This is a classic example of natural selection, where the fittest survive and pass on their traits to their offspring.## Step 4The other options (F, G, H) do not accurately describe the process of natural selection. They either suggest that the resistant insects change the toxin on the plants (F), grow larger and eat less (G), or eat the contaminated surface and leave the rest for others (H). None of these options explain how the pesticide becomes ineffective due to the presence of resistant insects.
