What information did the copper lizard models provide in the study of temperature regulation described earlier?

Expert Solution
Summary Introduction

To review:

The information provided by the copper lizard in the study of temperature regulation.

Introduction:

The regulation of temperature in lizards was studied by Paul E. Hertz of Barnard college. Lizards cannot regulate their body temperatures, so they respond to environmental changes. They maintain the thermal homeostasis by perching in the sun to warm up when the temperature is low. Paul E. Hertz, along with his colleagues, created artificial lizards of copper equipped with built-in thermometers.

Explanation of Solution

The researcher took the copper lizards to Puerto Rico and hung them at random positions. The temperature of the copper lizards was used to provide a null hypothesis. The researcher placed the lizard at random locations, so that it could provide information about the measure of sunny and shade in that particular habitat.

The temperature of the models also provided a null hypothesis about the temperature of lizards when they perch at random locations...
