Summer Assignment: Survival of the Sickest
Introduction (1)What is the “big” question the book will attempt to answer? "Why would evolution allow seemingly harmful genetics t be passed through the gene pool?"
Chapter I (2)The author points out many ways in which iron impacts life. Identify/describe at least five. 1. Hemoglobin to carry oxygen 2. oceans "seeded" with iron can hold more oxygen producing organisms. 3. Parasites feed on human iron. 4. Cancer cells thrive on human iron 5. High levels of iron can counter-act the effects of antibiotics, by feeding the bacteria to the point that they can live despite the antibiotics (3)In the context of this chapter, explain the author’s reference to Bruce Lee and to the barber pole. Bruce Lee is compared to the iron-deficient macrophages of the immune system because they are viewed as being inferior, as is Bruce Lee, but can kill better than their fully equipped counterpart in a human without hemochromatosis. The barber pole was the place to go for centuries in the west to be bled. The pole had all the aspects of this practice. The brass bowl at the top was representative of the bowl used for holding leeches that drew the blood, and the bowl on the bottom was for the collection of blood. The red and white stripes originated in the medieval times when bandages were hung on a pole to dry, giving them the twisted pattern. The author make this reference because a treatment for hemochromatosis is bloodletting, and this treatment dates back to medieval times.
Chapter II (4)Distinguish between each of the three types of diabetes. 1. Type 1 diabetes occurs when the body recognizes the cells that produce insulin in the pancreas as foreign and attack them. Without the insulin, the blood sugar level cannot be maintained. 2. In type 2 diabetes, insulin is not recognized or not produced to the levels needed to effectively absorb and convert blood sugar. 3. Gestational diabetes is usually
