how do crabs get disease why is prevealence different between sites when to use the lowest prevalence for a regression what is the hypothesis for disease prevalence in crabs how to test disease prevalence which is the least prediabetic crab species? what is the best method of building a regression model based on the least prevelence what is the hypothesis for the smallest disease prevalence what is the prevalence of disease in crabs which hypothesis is based on the least affected crab species which hypothesis can be tested for the least exposed crabs? what is the prevelence of disease in crabs can an unpolluted pollution environment cause low prevelence of diseases and apoptosis which hypothesis is the least prevessential in the most crabs? can disease prevalence varies by pollution source? what is the difference between disease prevalence and prevelence? what is the baseline prevelence of crabs how to test for prevelence how does disease prevalence vary from one site to another? what is the least exposed site for crab disease
