Exercise
Comparative Biology: Respiratory Surfaces
In this engaging exercise, students will explore the various respiratory surfaces found in different organisms, comparing the efficiency and adaptations of structures like gills, lungs, and skin. Through hands-on activities and interactive discussions, learners will gain a deeper understanding of how respiratory systems are tailored to environmental needs and evolutionary pressures.
