The eukaryotic cell at left is in the process of cytoplasmic division. Is this cell from a plant or an animal? How do you know?
In 2005, researcher Woo-suk Hwang reported that he had made immortal stem cells from human patients. His research was hailed as a breakthrough for people affected by degenerative diseases, because stem cells may be used to repair a persons own damaged tissues. Hwang published his results in a peer-reviewed journal. In 2006, the journal retracted his paper after other scientists discovered that Hwangs group had faked their data. Does the incident show that results of scientific studies cannot be trusted? Or does it confirm the usefulness of a scientific approach, because other scientists discovered and exposed the fraud?
1. As a science student, you're working in the lab using your compound microscope. The room is quite dim-lighted with only fluorescent lamp on. You're examining a plant cell with a light green color and it seems that it's hard for you to get a clearer view of its nucleus. What must be done to make your study successful? 2. Donating a pint of blood reduces blood volume, which results in a decrease in blood pressure (just as air pressure in tire decreases as is let out of the tire). What effect does donating blood have on heart rate? What would happen if a negative feedback mechanism did not return the value of some parameter such as blood pressure to its normal range? Please only answer these questions briefly. Thank you

5. Inspired by her biology lab, a student decides to make a closer study of the food she eats.
