Answer to Question 1

ANS: B
Chronic myelogenous leukemia is effectively treated with Imatinib mesylate. This drug inhibits most of the transforming capability stemming from the tyrosine kinase (P210) activity of the bcr/abl fusion gene. This P210 fusion protein is not found in the other myeloproliferative disorders, so the drug is ineffective in these disorders.

Answer to Question 2

ANS: C
Chronic myelogenous leukemia often progresses to acute leukemia, which may be either myeloid or lymphoblastic.

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.
