Cholera toxin, produced by Vibrio cholerae, a pathogenic intestinal bacterium, causes an indirect reduction in the activity of the Na /K ATPase in intestinal epithelial cells. This results in reduced uptake of small sugars and amino acids from the intestine. How is this reduction in uptake coupled to impaired Na /K ATPase function

Suppose a particular species of tulip plant has three alleles for the gene that codes for flower color. the cr allele produces red tulips, the cp allele produces purple tulips, and the cw allele produces white tulips. cr is dominant over cp and cw, and cp is dominant over cw. for each of the following crosses, determine the expected ratio of offspring for each flower color. cr cp x cp cw cr cw x cp cw 1 red: 1 purple : 0 white, 1 red: 2 purple: 1 white, 2 red: 1 purple 1 white, 1 red: 3 purple : 0 white, 2 red: 0 purple : 2 white, 2 red: 2 purple : 0 white
