Alma is planning on joining the track team this year. In preparation for the season, Alma decides she wants to start running on her own to get in shape. One day, Alma eats a granola bar and then runs a few quick laps around the track. How does her body obtain energy from food that will help her while exercising? Place the following events in order based on what is happening in her body's cells as she runs. A glucose molecule is broken down in the cytoplasm. Oxygen is used to break down smaller molecules. Smaller molecules enter the mitochondrion. A large amount of energy is released. A glucose molecule enters the body cell. Review progress Question 15 of 18 Back Next >

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.
