bacterial growth curve help

whats wrong with each graph using the chart provided.

The data used to construct these curves is given in Table 6-3. What is wrong with Figure 6.11? How would you fix it? nwns

Answer 1

Figure 6.10 The graph plot in semi log graph sheet. The Absorbance is decimal number so it don't need semi log graph, only ordinary graph sheet is enough.

Figure 6.11 The cfu/ml has higher value contain millions in the count. So in this data we need to use semi log graph to get the clear view on the graph.
