Textbook Question
Chapter 18, Problem 23RQ
In early research on the control of rhythmic breathing, scientists made the following observations. What hypotheses might the researchers have formulated from each observation?
- a. Observation. If the brain stem is severed below the medulla, all respiratory movement ceases.
- b. Observation. If the brain stem is severed above the level of the pons, ventilation is normal.
- c. Observation. If the medulla is completely separated from the pons and higher brain centers, ventilation becomes irregular but a. pattern of inspiration/expiration remains.

Case Study—Ella
Ella has a family history of diabetes. She wants to follow a healthful eating pattern that can lower her risk for developing this condition. Her dietitian recommends a goal of 450 to 600 kcal per meal and advises Ella to follow the Acceptable Macronutrient Distribution Range (AMDR) for carbohydrates and the Dietary Guidelines for Americans 2015-2020, which recommend limiting added sugar. She also recommends that Ella choose whole grains rather than processed grains. Ella decides to pack a lunch to take to work every day. This morning she’s making a sandwich for her lunch.

- Glitazones reduce insulin resistance by binding to a transcription factor in adipocytes, thereby reducing thesecretion of fatty acids. Glitazones are taken orally (in pill form). Using pharmacokinetic modeling, deriveequations to describe how the concentration of glitazones varies in the plasma as a function of time. Yourequations should be of the form: dCglitazone /dt = something, or dMglitazone /dt = something. Your model shouldinclude three compartments: the gut, the plasma, and the fatty tissues. Make sure to include a diagram thatillustrates your thinking, state all assumptions, and define your variables.

- In a population of Jackalopes (pictured below), horn length will vary between 0.5 and 2 feet, with the mean length somewhere around 1.05 feet. You pick Jackalopes that have horn lengths around 1.75 feet to breed as this appears to be the optimal length for battling other Jackalopes for food. After a round of breeding, you measure the offsprings' mean horn length is 1.67. What is the heritability of horns length (h2)? Is Jackalope horn length a heritable trait?
