BIOL 111: Concepts in Biology I

Discover the precise organization of thin and thick filaments in muscle cells as we debunk misconceptions and highlight the vital role of sarcomeres in muscle contraction.

Explore the composition of the diaphysis in long bones. Learn about the significance of compact bone in providing strength and differentiating it from other bone components.

Discover the debate between Intelligent Design (ID) and evolutionary science as they clash over the complexity of biochemical pathways in nature. Explore the concept of guided vs. unguided evolution and how diverse pathways challenge the ID perspective.

Learn how bioremediation works to treat contaminated environments and how microbes can help clean up pollutants. We evaluate multiple scenarios zeroing in on oil-degrading bacteria as a prime example of the process.

Explore the distinct characteristics of muscle tissues and their functions. Understand the differences between skeletal, cardiac, and smooth muscles. Get insights into the anatomy of striations, cell shapes, and nuclei.

Uncover the vital role of the kidneys in blood filtration and electrolyte balance. Understand the significance of the glomerulus, Bowman's capsule, and renal structures in the filtration process. Grasp the journey of filtrate as it becomes urine within the renal system.
