BIOL 20144: Evolution, Form, and Function of Organisms

Learn about the path of blood flow in the mammalian heart and circulatory system. Discover how oxygen-rich blood from the lungs enters the left atrium and understand why other statements about blood flow are incorrect.

Uncover why flamingos, genetically predisposed to white feathers, sport a pink hue. Dismissing influences like weather and DNA mutations, the mystery unravels with diet: the intake of carotenoids from their food which overrides their genetic blueprint

Discover which biochemical reaction liberates the most energy comparing options like oxidizing sucrose converting ADP to ATP and cellular respiration. This video offers detailed explanations of each reaction's energy output helping you understand their roles in biological systems.

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.

Explore the distinct approaches of bioremediation and biological augmentation in managing environmental issues. Learn how organisms are utilized for pollutant degradation or enhancing ecological functions to mitigate environmental degradation.

Explore the key concepts that might illustrate the unity among all organisms including emergent properties descent with modification and natural selection. Understand why the structure and function of DNA ultimately stand as the best example of this unity
