Several models were considered to predict whether students would be accepted to a certain medical school. Variables were Acceptance (0=no, 1=yes), Sex (0=female, 1=male), MCAT score, and GPA. Below are the results from fitting one particular model. Find (or give the expression for finding) the estimated probability of acceptance for a female student with GPA 3.0 and MCAT score 32?     > summary(glm(Acceptance ~ GPA + MCAT + Sex, family=binomial(link=logit)))    Coefficients:                Estimate Std.

The MC1R protein is a transmembrane protein involved in signal transduction; the mutations you identified are found in both the extracellular and intracellular domains. Based on what you know about signal transduction, which two of the following are the most likely explanations for how these mutations result in changes in this signaling process leading to changes in pigment production?
