Why do you think your new patient, Elisa, is feeling tired all the time? Explain your ideas.

Elisa’s cells are getting enough oxygen and amino acids, but not enough glucose. Her digestive system should break down starch molecules into glucose molecules, which are small enough to get into cells, and her circulatory system should deliver the glucose to cells. Students diagnose Elisa with diabetes.

Explanation:

They explore several medical conditions with the Sim and through text. They conduct a handson investigation and participate in a Classroom Body Systems Model. They explain how diabetes affects Elisa’s body systems and the molecules that get to her cells.

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
