LSC 314: HIV/AIDS: Science, Behavior, Society

Explore the intricacies of muscle contraction and the pivotal role played by elements like Calcium, Sodium, Potassium, and Chloride. Learn how Calcium directly triggers contraction by interacting with troponin and actin filaments. A thorough breakdown of each element's unique contribution to our body's movement.

Explore what makes each element unique by focusing on the atomic components: protons neutrons and electrons. Learn why the number of protons known as the atomic number is the defining characteristic for each element's properties. Understand how protons set elements apart even as neutrons and electrons also play important roles.

Explore the key concepts that might illustrate the unity among all organisms including emergent properties descent with modification and natural selection. Understand why the structure and function of DNA ultimately stand as the best example of this unity

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.

Discover the evolution of plant-eating habits in insects, the links between moths, butterflies, caddisflies, flies, and fleas. Explore the hypothesis of how herbivory could influence speciation and diversity within the insect kingdom.

Unlock the intricacies of kidney function as we focus on the role of nephrons and their specific components in regulating water recovery or disposal. Understand how collecting ducts are the main player in this process and debunk common misconceptions about other nephron parts.
