Clarify question:
What is the key concept addressed by the question?
The key concept is to identify the characteristic that of bacteria that makes them better able to adjust to changing environmental conditions.
What type of thinking is required?
This is an application question, you will need to apply what you know about selection to the situation being presented.

What do you already know about the characteristics of bacteria that might allow them to respond to changes in their environment? What other information is related to the question?
Selection acts to favor the best adapted individuals, these individuals reproduce and pass their genes to the next generation. Bacteria can reproduce every 20 minutes given enough resources. Fish cannot reproduce nearly as fast.

Given what you now know, what information is most likely to produce the correct answer?
The shorter generation time in bacteria is going to allow them faster adaptation to a changing environment.
Reflection on Process:
Did your problem-solving process lead you to the correct answer? If not, where did the process break down or lead you astray? How can you revise your approach to produce a more desirable result?
Were you able to identify the shorter generation time as being the factor that will give bacteria the advantage in adapting to a changing environment?

Albinism is a recessive disorder in which the skin and hair fail to produce pigment. The following question(s) ask you to evaluate the pedigree chart shown here in which "N" is the allele for normal pigmentation and "n" is the allele for albinism. The shaded circles for Deirdre and Shannon represent the only individuals expressing the disorder.
What was the probability that Deirdre and Geoff's first child would express the albino trait?
A. 1/2 B. 3/4 C. 1/8 D. 1/4
