Check my answers. i put them under the comments. cells can make new cells. one cell can (a) into two new cells. this is called ( the process of cell division goes through various states. first, the cell nucleus ( into two. a new cell surface membrane then ( the cell divides. the two new cells are called ( and they are small. the will grow and become larger. they grow by getting ( from the food that is eaten. once they grow to full size they can also ( if cells divide more quickly than they should, or divide in the wrong way, ( can develop.

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.
