Use Science Graphics

Pancreatic secretions contain sodium bicarbonate and enzymes. The graph shows the secretions of the pancreas in response to three different substances in chyme. Use the graph to answer questions 29 and 30.

A bar graph titled 'Pancreatic secretions'.dd

  1. Interpret Graphs Each pair of bars represents the response of the pancreas to a different variable. What are the three variables?

  2. Analyze Data Compare the composition of pancreatic secretions in the presence of hydrochloric acid and fat.

Write About Science

  1. Creative Writing A children's television workshop wants to explain the process of digestion to young viewers. You are asked to write a script that describes the travels of a hamburger and bun through the digestive system. Write an outline of your script, including information about what happens to the different nutrients in each part of the digestive system.

  2. Assess the Using Figure 30–2, choose five body systems that are involved in maintaining homeostasis in your body as you answer these assessment questions. Explain how these five body systems work together.

Analyzing Data

MyPyramid classifies food into six categories: grains, vegetables, fruits, milk, meat and beans, and oils. Personalized eating plans can be found at mypyramid.gov. This pyramid contains daily recommendations for Ryan, a 15-year-old male who weighs 140 pounds, is 5 feet 7 inches tall, and is physically active about 30 to 60 minutes a day.

  1. Predict If Ryan were to become less active, what would happen to the number of extra Calories he could consume? Explain.

  2. Infer For Ryan to meet his grain requirements, which group of foods would be his BEST choice in a single day?

    1. sweetened cereal, pasta, white bread

    2. whole-grain bagel, a doughnut, and pasta

    3. whole-grain cereal, potato chips, and whole-grain bread

    4. oatmeal, whole-grain bread, and a sweet potato
