During science class, students were instructed to develop a dichotomous key (a tool that allows the user to determine the identity of items in the natural world) in order to classify organisms into one of the six kingdoms of life. ms. king, their teacher, provided them with this diagram. according to the diagram, the best way to separate all living things into two main groups would be to consider a) method of reproduction. b) consumer versus producer. c) cell type, prokaryotic versus eukaryotic. d) organization, unicellular versus multicellular.

Ali hypothesized that increasing fertilizer would increase plant growth. four groups of thirty similar plants were given 0 to 15 ml of fertilizer, as shown in the graph. the change in plant height for each group over a two-week period was averaged and recorded. plant group fertilizer added (ml) avg. growth (cm) a 0 4 b 5 6 c 10 8 d 15 3 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.
