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?
She will perform a second investigation on the role of certain genes in disease resistance.
She will revise her hypothesis to pertain to mutations rather than diet, and update her data accordingly.
She will use this information to determine that her original question was nonscientific, so she will revise it
She will determine that her hypothesis was not supported because resistance must be genetic.

Astudy by solloch and et. al., in 2017, gives the map above which shows the frequency of alleles with a ccr5-delta32 mutations over 87 different countries. this mutation deletes the presence of a co-receptor (ccr5) on the outside of human t-cells (lymphocytes). some viruses, such as the one responsible for the black death and human immunodeficiency virus (hiv), require this receptor for attachment to host cells during the infection process. the black death was an epidemic that passed over northern europe during the 14th century killing nearly 60% of europeans. according to this information, which explanation best explains why northern europeans show a greater immunity for hiv than some other parts of the world?
