CBIO 2200: Anatomy and Physiology I

Explore how viruses replicate and the various ways in which new viruses emerge. Understand the importance of mutation, cross-species transmission, and the significance of wider spread in host species for disease control strategies.

Explore the mysterious rise of MRSA following a battle against S. aureus with methicillin. Delve into various theories, and uncover the power of natural selection in shaping bacterial communities.

Discover the unique adaptations of C4 and CAM plants in photosynthesis. Understand their evolved strategies to fix carbon efficiently in challenging environments. Dive into nature's remarkable mechanisms of survival and adaptation.

Learn why lipid-soluble signaling molecules like aldosterone only impact specific target cells. We discuss four theories and reveal that intracellular receptors present only in target cells are the key. This video demystifies the unique mechanism behind aldosterone's selective action.

Learn about the role of Erythropoietin (EPO), a natural kidney hormone, in controlling red blood cell production and oxygen transport. Discover how athletes misuse synthetic EPO for performance enhancement, despite the associated health risks.

Explore the application of parsimony in constructing phylogenetic trees, emphasizing simplicity in scientific explanations and its relation to evolutionary changes. Learn about various options for tree construction and the core concept of choosing the most parsimonious representation
