Every normal curve should have 4 distinct phases. From my own opinion I think option D shouldn't be the answer since its a characteristic of a growth curve.

I feel the environment mustn't be stable. What about option A?

The option D is correct because the growth curve contains 5 phases; -lag, -log (expl), -stationary, -death and -prolonged decline phase. It is plotted with log (number) vs time.

The option B is correct because from what I know the logarithm number does not indicated on the growth curve, but the growth curve is related to logarithmic curve as it grow.

C is the correct answer. All other options are true for growth curve. It is ploted with log Vs times and not with graph number Vs time. Thanks.

I think the answer is B. Because growth curve with the solid line but growth curve for the expontential phase is plotted logarithmically.

I think the answer is A. Because D can't be the answer as a curve as 4 phase lag log stationary and death.

So I think the answer is A.

But each curve is made up of the lag phase, exponential phase(log) stationary phase and death phase(4 phases).

I know each curve has the lag phase, exponential phase, stationary phase, and decline phase(4 phases)

Some endospore-forming bacteria have a survival phase. It is the 5th phase of the growth curve.

Curve has 4 phases. That's correct answer is B.

Growth will occur in stable environment.
