Textbook Question
Chapter 37, Problem 1RQ
What are some reasons a species may be absent from a habitat or region to which it should adapt well?
Expert Solution & Answer
Summary Introduction
To determine: The reasons for the absence of species from a particular habitat or area to which it should adapt well.
Introduction: The geographical distribution of the species can be explained with the help of fossil records. The fossil record indicates that some animals once flourished in the habitats that they no longer cover.
Explanation of Solution
The following are the reasons for the absence of species from a particular habitat or region:
- Some species become extinct through hunting.
- Some species prevent other species from colonizing in a particular region.
- Some physical barriers to the spread of the species are also one of the reasons.
- Environmental changes in a particular habitat also affect the species.

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.

- In Drosophila, an X linked recessive mutation, scalloped (sd), causes irregular wing margins. Diagram the F1 and F2 results if a (a) scalloped female is crossed with a normal male; (b) a scalloped male is crossed with a normal female (assume the female is homozygous). Compare these results to what you would find if the trait was not sex linked.arrow_forwardCase Study—Ella Ella has a family history of diabetes.

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.
