BIOL 110: Principles of Biology I

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.

Grasp the fundamentals of how neurons transmit electrical signals through action potentials. Understand the crucial role of myelination and fiber diameter in efficient nerve impulse conduction. Dive into the comparisons of different nerve fiber types and their properties.

Discover the complex world of sea urchin reproduction, focusing on the essential role the cortical reaction plays in egg fertilization. Uncover common myths surrounding this process and learn what actually happens at the cellular level. Gain insight into how the formation of a fertilization envelope is crucial for successful fertilization.

Explore active and passive transport and understand how ion pumps and phagocytosis fit in. Discover endocytosis as an active transport where cells engulf particles. Differentiate between active transport mechanisms and passive methods like facilitated diffusion.

We explore how to determine the nature of a mysterious, gelatinous substance found on a forest rock. By conducting a series of tests, including microscopy, DNA staining, respiration observation, and growth experiments, we aim to unravel whether this enigmatic material is alive, inanimate, or a product of a living organism.

Explore the significance of tracking same-age cohorts in population ecology. Learn how it aids in understanding birth and death rates, predicting population trends, and uncover the reasons behind this crucial ecological research practice.
