Globally, the winter of 2014–15 was the warmest winter on record at that time, but it sure didn’t seem that way for most of the eastern united states. this region experienced record-low temperatures and extreme snowfall, especially in the northern and coastal areas. during this period of extreme cold and snow, it was not uncommon to see comments on social media disputing climate change. for example, some commenters took pictures of huge piles of snow and added comments such as, "this doesn’t look like global warming." do these commenters have a point? should extreme snowfall over the course of a season cast doubt on the theory of global climate change? make a scientific argument explaining why you agree or disagree with these commenters.

Which of the following is an advantage of solar energy?

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.
