Which of the following is a limitation of the model shown above?
A The model shows synthesis of new compounds.
B The model is insufficiently labeled
C The model represents two different processes rather than one.

The fish shown above is a tarpon. it is a fast-swimming and powerful open-water fish. its closest relatives, oddly, are burrow-dwelling conger eels that stay on the bottom. both eels and tarpon developed from snake-like larvae that float in the plankton during the first stages of life. once they mature, tarpon and eels are not found near one another in the ocean. the tarpon and the eel illustrate all of the following except

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.
