Intake and absorption (proteins, tannins, coumarins and phenolics)

In this module, students will:

  • Understand the relevancy of toxin and nutrient absorbance to understand the physiology of animals.
  • Use scientific practices to quantify and compare toxin absorbance by animals.
  • Understand how the environment and animal morphology influences the physiological process of absorption.
  • Archive digital data on toxin absorbance by your animal for future iteration, collaboration and discovery.
