Students in a biology class were asked to draw a model that represents their understanding of why mitosis occurs in eukaryotic organisms. Four student’s models are presented below, and each model is supported by the student’s explanation of their thinking. Which model best represents our current understanding of the purpose of mitosis?

What is the best conclusion based on this data? the hypothesis was not supported because the data indicated that fertilizing plants does not improve plant growth. the hypothesis was supported; to get the best growth, use 5 milliliters of fertilizer per plant. the hypothesis was not supported; the data indicated that too much fertilizer can inhibit plant growth. the hypothesis was supported; to get the best growth, use 15 milliliters of fertilizer per plant.
