Which of the following best represents the relationship of the concentration of hydrogen ions between water, vinegar, and ammonia when mixed together in a solution? image shows a venn diagram with three circles. the water circle, indicated as neutral, overlaps the ammonia and vinegar circles. the vinegar circle, indicated as acid, overlaps the water and ammonia circles. the ammonia circle, indicated as base, overlaps the water and vinegar circles. image shows a vertical ph scale numbered from 0 to 14 with 0 at the top and 14 at the bottom of the scale. an arrow beside the scale indicates that as hydrogen-ion concentration increases the ph is reduced. the ph scale includes ammonia-at a ph of 11, water-at a ph of 7, and vinegar-at a ph of 2.5. image shows a segment of a horizontal ph line, with vinegar on the left side of the line, water in the center, and ammonia on the right side of the line. image shows a bar graph with three substances and their ph levels charted. the bar labeled vinegar has the lowest height. the bar labeled water is the second lowest height. the bar labeled ammonia is the tallest.

The tasmanian devil, a marsupial carnivore, is facing extinction due to devil facial tumor disease (dftd) which causes bulging cancerous lumps and lesions to erupt around the face and neck — often causing enough deformation to make seeing or eating difficult. dftd has evolved into a contagious cancer, a trait that is unique among cancers. devil mating behavior involves biting around the head and neck, allowing cells from one individual — especially cells from the crumbly dftd tumors — to be transferred to the wounds or face of a new individual. this marsupial was once found across australia, but sea levels rose, isolating the tasmanian population, while the australian population went extinct. what would be an outcome of genetic isolation that is likely to have impacted the spread of dftd? a) reduced territory puts diseased individuals in greater contact with non-diseased ones. b) inbreeding results in less variation in facial features so the cancer is generally fatal. c) genetic isolation has made it difficult for scientists to develop a vaccine against dftd. d) the lack of genetic variation in the immune system of tasmanian devils minimizes resistance to the disease.
