Question

growth rates provide his whole information because they can tell us something about optimum growth conditions. For example if you were a plot a series of growth curves at various temperatures and calculate the growth rates, you could generate a graph similar to the one at the right.

what is the original growth curve in part 1 obtained at the optimal temperature for this organism? If yes, explain how you knew. if not, can you tell at what temperature the growth curve is determined.

Growth Rate (h) 10 66 50 20 30 40 Temperature (°C)

Answer 1

From part 1, Growth rate can be calculated as 0.6 h^-1. And doubling time is 0.68 hrs.

No, the original growth curve in part 1 is not obtained at the optimal temperature of this organism. Because the optimal growth rate is around 3 h^-1 but here it is very less i.e 0.6 h^-1.

From 1st graph we can observe that 0.6 h^-1 can be correlated to either 12 ^oC and 49 ^oC (approximately). So, the growth curve is determined at 12 ^oC or 49 ^oC.

I got your question bit confusing. I have answered as far as I have understood. Sorry for inconvenience. Thank You.
