The survivorship curves of the American robin, a type of migratory songbird, and the common green darner, a type of migratory dragonfly, are shown below. What statement is best supported by the survivorship curves? A. A very high proportion of common green darners reach adulthood and live to older ages. B. Younger American robins have higher death rates than older American robins, while younger and older common green darners have similar death rates. C. American robins have a high survival rate for most of their lifespan and then decline rapidly in old age. D. American robins have similar death rates throughout their lifespan, while the death rate of common green darners changes over their lifespan.

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.
