BIOL 100: Principles of Biology

Explore the pivotal role of enhancers in gene expression as we dissect their function and interaction with transcription factors. Gain insights into how they crucially influence the transcriptional control of genes.

Unlock the secrets of ATP's essential role in powering life's processes. Discover why ATP is a specialized molecule that stores energy for your cells. Learn how to differentiate between common misconceptions and the real function of ATP.

Unpack the intricate processes within photosynthesis and identify which is most directly powered by light energy. Discover the critical role of chlorophyll in capturing solar power.

Discover the concept of negative feedback loops in biological systems, where balance is maintained by counteracting changes. Explore the four key components: Stimulus, Sensor, Control Center, and Effector, through examples like blood sugar regulation. Uncover how these loops play a crucial role in keeping our body systems in harmony.

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 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
