Early settlers in the town of dry gulch drilled wells to pump as much water as they wanted from the single aquifer beneath the town. (an aquifer is an underground body of water.) as more people settled in dry gulch, the aquifer level fell and new wells had to be drilled deeper at higher cost. residents of dry gulch have a private incentive to water because
a. over use; external costs aren't considered. b. under use; it is a scarce resource. c. over use; it is a scarce resource. d. under use; it is characterized by increasing marginal costs.

What happens whenever a net force acts on an object

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.
