BIOL 140: Fundamentals of Human Anatomy

Explore stromatolites, the oldest indicators of life on Earth formed by microbial actions. Understand their presence in shallow marine environments and their connection to early eukaryotic life.

Discover the concept of adaptation in this video, where we evaluate four scenarios to determine which represents a heritable trait enhancing an organism's survival in its environment. Learn how the webbed feet of a duck exemplify a true adaptation, enabling it to thrive in its habitat.

Explore the intricate process of mitosis and the crucial role it plays in cellular division. Learn how cell cycle control mechanisms, including cyclin degradation and Maturation Promoting Factor (MPF) activity, ensure accurate and regulated cell division.

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.

Deepen your understanding of glycolysis, a foundational cellular metabolism process. Grasp how glucose transforms into pyruvate or lactate, based on the presence of oxygen. A clear insight into this process aids in exercise science and disease research.

Explore the concept of semiconservative DNA replication, where each new DNA molecule retains one original strand. Understand the significance of this mechanism in ensuring accurate genetic information transfer across cell generations.
