How did louis pasteur’s experiments lead to new scientific understandings of germs? experiments with cooking food showed that disease-carrying germs in food could be killed when heated. experiments with different magnification lenses showed that germs were real and could be observed. experiments with animals showed that dominant genes could lead to risks of disease. experiments with shallow dishes showed that groups of germs could be grown so they could be seen without microscopes.

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?
