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.

1. this system transports blood through the body and heart. 2. this system relates to the process by which an organism gets rid of its waste. 3.this system is responsible for movement of bones and fluids throughout the body. 4. this system receives and transmits information and responses. it depends upon electrical impulses created by the movement of charged particles. 5. this system relates to the process by which an organism replicates. sexually reproduction usually involves male cells (sperm) meeting female cells (eggs) to produce a fertilized egg or zygote. 6. this system gets oxygen to the cells of the body and rids the body of waste gases. some organisms use their skin. this is also a cell-level process. 7. this system relates to the structure and support of an organism. it is made of salts and proteins and found in vertebrate animals. 8. this is the system of organs which circulate blood around the body of most animals. 9. this system controls the glands that secrete hormones. 10. this organ system to protect the body from damage. itembank : system circulatory digestive system endocrine system excretory integumentary system muscular system nervous system reproductive system respiratory system skeletal system cardiovascular system
