BIOL 01203: Biology 3: Cell Biology

Explore the indispensable role of decomposers in ecosystems. Understand their impact on nutrient cycling, energy flow, and ecological balance. Realize what Earth would face without these vital organisms.

Learn about the unique adaptability of facultatively anaerobic cells in different oxygen conditions. Discover the outcome of an experiment comparing their growth in aerobic and anaerobic environments. Grasp the resilience of these cells and their growth mechanisms.

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.

Discover the evolution of plant-eating habits in insects, the links between moths, butterflies, caddisflies, flies, and fleas. Explore the hypothesis of how herbivory could influence speciation and diversity within the insect kingdom.

Venture into the intricate mechanisms of a eukaryotic cell as we clarify the conditions under which transcription begins. Discover the pivotal role of the promoter and the essential docking of transcription factors.

Explore the groundbreaking heterotroph hypothesis by Alexander Oparin. This video outlines how the first organisms likely consumed pre-existing organic matter reshaping how we think about the origins of life and evolution
