QUESTION 1: Anemia is a disease that is caused by abnormally low hemoglobin levels or too few red blood cells. What do you think happens in the body cells of people who are anemic that makes them feel tired and weak? Please read the notes before answering this question!

QUESTION 2: Each minute, 300 million of your body cells die!!! (Don't worry - these cells are replaced by mitosis, or you would be dead in a very short time!) However, some of the body's cells last for years, and some divide every day. List three types of cells in your body you would think would be replaced frequently. List 2 types of cells you think would be replaced slowly, if at all.

QUESTION 3: When cancer starts to spread throughout the body, one course of treatment is chemotherapy (read more about it in this week's Good For!). One very obvious effect of chemotherapy is that people generally lose all of their hair a few weeks after the drugs enter their system. Why do you think chemotherapy drugs cause a person's hair to fall out?

QUESTION 4: Please answer this question: Do you enjoy reading the "What is Biology Good For" assignments? Do the Good Fors help you connect biology to the real world? Do your other classes help you connect the subject matter to the real world?
