Remember that cancer involves the loss of control of the cell cycle. This can happen in a variety of ways, but can often involve a change in a tumor suppressor gene or in a proto-oncogene. Considering the differences between these control mechanisms, discuss whether the following proteins are likely to come from a tumor suppressor gene or from a proto-oncogene. Justify each response in a manner worthy of 4 points. The articulation of your reasoning is just as important as the correct answer. Proteins involved in signaling pathways that activate proliferation (cell division)A protein that recognizes and fixes double-strand breaks in DNAA specific transcription factor that represses the promoters of genes involved in cell proliferationA protein that initiates apoptosis (programmed cell death)

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.
