Question

The number of bacteria growing in an incubation culture increases:

a) Logarithmically
b) Exponentially
c) Linearly
d) Erratically

Answer 1

The number of bacteria growing in an incubation culture increases exponentially.

Step-by-step explanation:

The number of bacteria growing in an incubation culture increases exponentially.

During the logarithmic (log) growth phase, bacterial cells divide by binary fission, with their number increasing exponentially. The growth curve is often plotted on a semilogarithmic graph to show a linear relationship. This exponential growth continues as long as there are no limiting factors present.
