John stimulated his earthworm twice with a stimulus interval of 1ms and a voltage above threshold for the median axon (but below threshold of lateral axon). he only saw one biphasic waveform response. explain what is occurring inside the median axon to prevent the second biphasic waveform. also, how many action potentials do you expect are being generated by his stimulation?

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?
