BIOL 1: General Biology

Discover the intricate details of the pelvis anatomy as we analyze and correct misconceptions about its structure and components, using sketches for clarity.

Unravel the origins of blood cell types as we differentiate between myeloid and lymphoid stem cells, highlighting the unique lineage of platelets, B cells, and Natural Killer cells.

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 fascinating interaction between electrical energy charge and materials through the lens of an electroscope. Discover how inserting a conductor between its charged foil sheets changes the charge dynamics leading to an attraction between foil and needle. Understand the roles of conductors insulators and charge induction in this intriguing experiment.

Explore the world of proprioceptors specialized sensory receptors in joints muscles and tendons that help us sense body movement and position. Understand the key types such as muscle spindles tendon organs and joint kinesthetic receptors. Learn why tactile discs are not considered proprioceptors even though they are sensory receptors

Discover the distinctions between mixtures and solutions in chemistry. Through everyday examples and a visual aid, grasp the relationship between these two concepts. Comprehend how mixtures and solutions are intertwined, yet uniquely different.
