Consider each of the research questions below and write a declarative statement null and alternative hypothesis for each a. Research scientists are interested in whether the pod shape gene (round vs. indented) and the flower color gene (purple vs. white) are inherited in a Mendelian fashion. The scientist crosses a pea plants that are heterzygous for both traits (i. e. heterzygous at both loci). To access if these genes are inherited in a Mendelain fashion, the researcher want to determine if the observed phenotypic ratio diplay by the offspring they breed is similar, to the expected 9:3:3:1 phenotypic ratio that is expected to result for a dihybrid cross where both genes are inherited in a Mendelian fashion.
b. You buy five small packages of multicolored chocolates and five small packages of peanut butter candies (which are the same net weight as the multicolored chocolates). You want to test if the mean number of candy pieces per package is the same between the two brands

Hey me with this one❤☺❤ how do you say that a cell also has a life span and death like an organism? give one example.

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.
