BIOL 202: Principles of Biology LEC

Discover the distinct identity of elements as we clarify the smallest unit that embodies their unique properties. Breaking down options such as electrons, isotopes, and elemental particles, this video offers a clear explanation of why atoms stand out.

Unlock the language of genetic history with our guide to understanding pedigrees and their symbols. Learn how to interpret squares circles and lines to track inheritance patterns for traits and diseases.

Explore the distinctions between aerobic, anaerobic, and non-aerobic exercises. Understand the energy mechanisms driving each type of exercise and their unique health benefits. From jogging and sprinting to golf, discover how each engages the body differently.

Explore the processes behind ATP synthesis during oxidative phosphorylation. Learn the pivotal role of the proton gradient in energizing ATP synthase. Visualize the interplay of cellular components producing the ATP symphony.

Learn about the critical roles of the epiglottis and glottis in our respiratory and digestive systems. Understand how the epiglottis acts as a protective gate during swallowing, while the glottis facilitates sound production. Together, they ensure safe breathing and swallowing.

Explore the critical role of phospholipids in forming cell membranes across various organisms. Understand their unique amphipathic properties and their influence on cellular processes, from transport to signaling.
