1. Illuminate (investigate, illustrate {draw, diagram, print}, describe, and explain) what scientists have discovered regarding the major biological, ecological, and behavioral adaptations associated with each of the following primate groups. Be sure to tell in what geographic areas the fossil evidence of each form has been found and what scientists think the areas were like when the fossil forms lived there. For the hominins that used stone tools, illustrate and describe typical examples of their technology.

Ms. Johnson, age 57, was referred to the gastroenterologist for chronic digestive problems. For at least a year, she said, her stomach ached after eating a small meal. It seemed like the dull pain she experienced, and the sensation of fullness, had increased recently. Ms. Johnson also felt abdominal cramping, and sometimes nausea, at times other than after eating.

After taking a complete history and performing a physical examination, the gastroenterologist ordered several tests. Her conclusion was that Ms. Johnson had chronic gastritis caused by an infection with a bacterium.

QUESTIONS

1. Which bacterium is the most common cause of chronic gastritis?

2. Explain how the bacteria survives in the harsh acidic environment? (mention the enzyme it uses and how it causes damage)

3. What is the pathophysiology behind chronic gastritis?

4. What are the protective factors in the stomach?

5. What are the damaging factors in the stomach?

6. What other conditions (other than the bacteria) can cause chronic gastritis?

7. Mention at least two manifestations and two complications of chronic gastritis.

8. What is peptic ulcer disease? How is it different from gastritis?
