In an Experiment,a Researcher Infuses a Solution of Conjugated Bile

In an experiment,a researcher infuses a solution of conjugated bile acids into the portal vein of a rat so that their normal concentrations are approximately doubled.He collects samples of hepatic bile from the rat before and after the infusion.Before the infusion,the concentrations of bile acids,phosphatidylcholine (PC) ,and cholesterol (chol) are 30,9,and 3 units per milliliter.What would be the predicted concentrations of PC and chol in the bile after the infusion of bile acids?

A) PC: 9 U/mL; chol: 3 U/mL
B) PC: 18 U/mL; chol: 3 U/mL
C) PC: 9 U/mL; chol: 6 U/mL
D) PC: 18 U/mL; chol: 6 U/mL
E) PC: 3 U/mL; chol: 9 U/mL
