BIOL 1108: Principles of Biology II

Discover the fundamentals of the respiratory system and the primary muscle behind inspiration. This video breaks down the physiological process of breathing, the key role of the diaphragm, and why other muscles don't initiate breathing.

Discover the body's innate ability to adapt to extreme cold conditions. Learn how the brain orchestrates warming responses like shivering. Grasp the concept of homeostasis in maintaining internal stability.

Unravel the intricacies of mitosis by identifying each phase and their characteristics. Highlight the process that is not a part of mitosis, emphasizing the importance of DNA replication.

This data-driven video examines the difference in nucleotide replication rates between prokaryotes and eukaryotes, providing insights into the factors affecting their speed. It concludes that prokaryotes outpace eukaryotes, replicating nucleotides approximately ten times faster, and explores the contributing factors behind this difference.

Discover the science behind thermoregulation, focusing on endotherms and ectotherms. Understand how internal metabolic processes distinguish endotherms, while ectotherms rely on environmental factors. Highlighting the adaptations each group has evolved to thrive in their habitats.
