BIOL 160: Cellular and Molecular Biology

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.

Primary succession is the process of converting barren, lifeless rock into a flourishing terrestrial community. This ecological transformation begins with pioneering species and lays the foundation for complex ecosystems.

We explore how to determine the nature of a mysterious, gelatinous substance found on a forest rock. By conducting a series of tests, including microscopy, DNA staining, respiration observation, and growth experiments, we aim to unravel whether this enigmatic material is alive, inanimate, or a product of a living organism.

Explore the influence of atmospheric pressure in our body's functions, particularly its essential role in pulmonary ventilation or the breathing process.

Explore the foundational processes of aerobic and anaerobic respiration. Uncover the key roles of glycolysis, the citric acid cycle, and oxidative phosphorylation. Differentiate between the efficiencies and electron acceptors of both respiration types.

Discover the essence of hydrostatic pressure and its significance in capillary beds, examining its relationship with colloid osmotic pressure and how it affects fluid movement in our circulatory system.
