A scientist conducted an investigation about the effects of diet on disease resistance in mice and made surprising observations. The mice with a genetic ear mutation seemed to show similar patterns of resistance compared to mice with normal ears. Based on this information, what will the scientist most likely do next?
Answer
A
She will perform a second investigation on the role of certain genes in disease resistance.
B
She will revise her hypothesis to pertain to mutations rather than diet, and update her data accordingly.
C
She will use this information to determine that her original question was nonscientific, so she will revise it.
D
She will determine that her hypothesis was not supported because resistance must be genetic.
Explanation
Because the mice with and without the ear mutation showed similar resistance patterns, the mutation may not explain the results. The scientist should investigate further, including whether particular genes affect disease resistance. A second investigation can help test that possibility; she should not change or discard the data to fit a revised hypothesis.
