The Figure Shows a Hypothetical Relationship Between the Growth Rates

Multiple Choice

The figure shows a hypothetical relationship between the growth rates of E. coli at 37 and 42 degrees Celsius. This figure illustrates what type of evolutionary constraint?

B) It illustrates the lack of repeatability in evolution.
C) Alleles that are beneficial in one environment may be deleterious in another environment.
D) Changing environments make it impossible for natural selection to act.
