Question
The chapter's example of bacteria surviving a heat wave illustrates that
heat-resistant bacteria survive better, showing how variation aids survival
all bacteria die equally in a heat wave
heat has no effect on bacterial populations
only sexually reproducing bacteria can survive heat
Answer
heat-resistant bacteria survive better, showing how variation aids survival
Detailed Explanation
The chapter reuses the earlier example that bacteria able to withstand heat will survive better in a heat wave, illustrating survival advantage from variation.
