Survival Of The Sickest Chapter 1 THADDEUS MILLER

Survival of the Sickest by Dr. Sharon Moalem
Biology Intro to Evolution 1.
You will be assigned a chapter to read from Survival of the Sickest and be expected to answer questions regarding your reading in your own words (do not copy word­for­word from the book). 2.
Use good grammar and spelling, full sentences and be clear and concise. 3.
You need to start talking and writing like a biologist. By this, I mean your answers need to use appropriate biological terms and demonstrate a thorough understanding of the key concepts. Incomplete sentences, answers of a single sentence or a few words, answers that just skim the surface
WILL NOT
WORK FOR THIS ASSIGNMENT. 4.
For this assignment, several questions will require answers to be a paragraph or two. A typical paragraph consists of 4­5 sentences. If you do quality work you will probably write MORE than two paragraphs for a number of your responses. 5. Be sure to use the spell check function before submitting your assignment. Have someone else proofread your answers to make sure they make sense. 5.
Another key skill you will need is to use evidence to support what you claim. In science, your opinion holds very little weight, you must provide evidence to support whatever claim you make in response to a question. This does not mean copy something from the book word­for­word.
Whenever
you cite specific evidence or facts from the book that you did not already know, I want you to reference the page number from where you pulled that information in parentheses. EVERY answer will require you to make at least one or two citations. For example, I might make the following claim from the book, thus I will reference the page number as follows: In the 1300s people with hematochromatosis wer more likely to survive and reproduce because of their iron­starved macrophages. This means people with the mutation for hemochromatosis were more likely to pass on the defective gene to their children. So generation after generation, more and more people had the gene for hematochromatosis and possibly explains why the plague died out by
1350. (p. 15) Notice I did not copy this information word­for­word, but paraphrased it and put it into my own words.

You have been assigned Chapter 1 of the book
Survival of the Sickest.
Type your answers under each of the questions asked below:

Chapter 1 ­ Ironing it Out ­ Read pages 1­22 1. Define hemochromatosis and explain what conditions it can lead to. hemochromatosis­ The

condition in which an organism contains too much iron in their body. Many cells contain too much iron so other body cells may be deprived of iron, surprisingly.
A person can develop a couple diseases such as tuberculosis because it can use the iron from the macrophages.
2. Explain why the presence of oxygen is crucial to living lings. What does it do and how does our body protect itself from invading bacteria stealing it for its own purposes? Organisms use oxygen and mix it with food to make energy. It is also vital for photosynthesis in plants and cell respiration.
3. Explain what a chelator (kee­later) is.
4. What are macrophages and what do they do?
5. Who was most affected by the bubonic plague and why?
6. “What doesn’t kill us, makes us stronger.”
a. from an evolutionary standpoint, explain what this statement means
b. Describe TWO examples from chapter one that either support or refute the statement.
