One example: Question: A 13-year-old girl is operated on due to Hirschsprung illness at 3 months of age. Which of the following tumors is more likely to be present?
Options: <1> Abdominal neuroblastoma <2> Wilms tumor <3> Mesoblastic nephroma <4> Familial thyroid medullary carcinoma.
Solution is here: 2
Explanation: The answer to the given question should be a tumor, therefore Wilms tumor is the correct answer for the given question.

Now, solve this: Question: With respect to the distribution coefficient of a solute between two partially miscible liquids:
Options: <1> Because it is a quotient between solute concentrations in the two phases, it is independent of temperature. <2> It does not depend on the total amount of solute in both parts. <3> It is useful to determine the molar mass of the solute. <4> If one phase is water and the other an organic solvent, it is usually used in medical and environmental chemistry to know the distribution of drugs and contaminants between these two types of media. <5> It only has physical significance when the liquid phases are in contact through a semipermeable membrane.
Solution:
4
