BIOL 104: General Biology

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

Discover how humans adapt to cold environments through thermoregulation processes. Understand the body's heat conservation and generation mechanisms. Learn why certain physiological responses occur in cold conditions.

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.

Explore the intricate workings of the immune system's overactive responses, known as hypersensitivity reactions. Learn about the classification into Types I, II, III, and briefly, IV, along with real-world examples. Uncover the mechanisms behind these reactions and their impact on our health.

This video explores the distinction between innate and learned behaviors in animals. Innate behaviors are inborn and instinctive, while learned behaviors develop through experiences and observations, allowing animals to adapt to their environment and enhance their chances of survival.
