1. which statement is true regarding similarities and differences between aerobic and anaerobic respiration? (1 point)
a. they are similar because both produce the same number of atp molecules per glucose.
b. they are similar because both capture the bond energy of glucose in the bond energy of atp.
c. they are different because anaerobic respiration requires mitochondria and aerobic respiration does not.
d. they are different because anaerobic respiration always produces carbon dioxide as a waste product and aerobic respiration does not

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.
