Question

In our experiment we made 10-fold serial dilutions of a sample. We made both spread plates and pour plates. These are our final results from last semester.

Decide which of the following statemtents are true statements.

QUESTION 6 In our experiment we made 10-fold serial dilutions of a sample. We made both spread plates and pour plates. These are our final results from last semester. Dilution Factor Pour plates Spread Plates TMTC (300+) TMTC (300-) 10-2 TMTC (300+) 10-3 291 78 10-1 Decide which of the following statemtents are true statements. These results do not make sense because there should be 10x more colonies on spread plates compared to pour plates due to the volumes that were added during inoculation. These results do not make sense because there should be equal amount of colonies on spread plates and pour plates due to the volumes that were added during inoculation. The students who performed the 30 trials had excellent techniques/lab skills. These results make sense because the final calculations for the pour plates & the spread plates are relatively close in value. This makes sense because we only had 1 sample & therefore can not have 2 concentrations. These results make sense because the final calculations for the pour plates & the spread plates are relatively different in value. This makes sense because we had two samples & therefore should have 2 concentrations. These results make sense because there should be 10x more colonies on 10^-2 plates compared to the 10^-3 plates. These results make sense because there should be 10x more colonies on pour plates compared to spread plates due to the volumes that were added during inoculation. The students who performed the 30 trials need to improve their technique/lab skills. These results do not make sense because the final calculations for the pour plates & the spread plates are relatively different in value. This does not make sense because we only had 1 sample & therefore can not have 2 concentrations. These results do not make sense because there should be 10x more colonies on 10^-2 plates compared to the 10^-1 plates.

Answer 1

The results make sense because the final calculation for the pour and spread llage are relatively close in value. This makes sense because we had 1 sample and do not have different concentrations

291*10^3 in pour plate 78*10^3 in spread plate and relatively close
