Final answer:
To test two fertilizers, Grow Well and Green Grow, on tomato plants, Jason would likely divide the plants into two equal groups, using option C) Planted 25 with Grow Well and 25 with Green Grow, allowing for a controlled comparison.
Step-by-step explanation:
To assess the effectiveness of two fertilizers, Grow Well and Green Grow, on tomato plants of the same variety, Jason would need to divide the 50 plants into two equal groups. This would mean that option C) Planted 25 with Grow Well and 25 with Green Grow is the correct answer. By administering Grow Well to 25 plants and Green Grow to another set of 25 plants, and keeping all other conditions the same, Jason can conduct a controlled experiment. This method allows him to observe the results of each fertilizer without any confounding variables, as the plants are all of the same variety and grown under the same conditions.
Such an experiment is essential in scientific research to establish a causal relationship between the variable being tested (in this case, the type of fertilizer) and the outcome (the weight of tomatoes produced).
