What do you already know about erythropoietin? What other information is related to the question?
· As altitude increases, the oxygen that is available to animals decreases.
· Red blood cells are known as erythrocytes.
· Erythrocytes carry oxygen to the tissues of the body.
· A plasma protein is converted into erythropoietin in the kidneys.
· Erythropoietin stimulates the red bone marrow to make erythrocytes.
· Erythrocytes are made from stem cells.

Given what you now know, what information is most likely to produce the correct answer?
· The only function of erythropoietin is to stimulate the production of new red blood cells.
· This would increase the amount of oxygen that can be carried to cells, which would be important at higher altitudes where oxygen is less available.
Reflect on Process
Did your problem-solving process lead you to the correct answer? If not, where did the process break down or lead you astray? How can you revise your approach to produce a more desirable result?
· Apply level:
o Answering this question correctly depended on your ability to use the function of erythropoietin in a new situation. If you got an incorrect answer, did you remember that erythropoietin stimulates the redbone marrow, or that the red bone marrow produces erythrocytes? Did you have trouble extending the function of erythropoietin to determine the correct answer?
