Question

Quizplus · Accepted Answer

The rate of microbial death is constant for cells in a culture. This means that a fixed percentage of the population dies over a set unit of time. It is not true that cells die at increasingly greater rates, only older cells die, or all cells die at one time. While it is possible for some control agents to cause immediate and total cell death, it is not a general phenomenon. It is also not true that cells become metabolically inactive but are never killed, as control agents can kill cells by disrupting critical processes within them.
