Answer:
The correct option is C) III. That is, the trout will suffer from disease.
Explanation:
Note: This question is not complete as the options are not included. The complete question with the options is therefore provided before answering the question as follows:
A lake is home to a large number of trout. Identify what is most likely to happen if a chemical is dumped into the lake.
I. The trout will not be affected by the pollution.
II. The number of trout will increase.
III. The trout will suffer from disease.
A) I
B) I and II
C) III
D) II and III
The explanation of the answer is now provided as follows:
Natural selection is the process that took place in the lake. Only those trouts that were fit to survive, or those that have alleles that allow them adapt to new conditions, live and multiply in the presence of an external environmental effect like pollution. In such a circumstance, the fittest organisms would have survived, and the population's allelic frequency would have grown through time. Due to pollution, creatures harboring the other alleles died, causing the total frequency of alleles to alter.
Therefore, the correct option is C) III. That is, the trout will suffer from disease.
