When maintaining homeostasis in mammals antidiuretic hormone ( ADH ) is essential . In response to elevated tissue osmolarity ADH is released from the hypothalamus . The collecting duct and distal tubule in the kidney become more permeable to water in response to ADH , which increases water reabsorption into the capillaries . A negative feedback loop regulates the quantity of hormones released Which of the following statements reflects the proper relationship between osmolarity release of ADH and production of urine depending on the model presented ?

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?
