BIOL 111: General College Biology

Uncover the intricacies of adaptive radiation, the rapid diversification of species into new ecological niches. Understand factors that drive this phenomenon and how genetic drift stands as an exception. Learn the role of evolutionary innovations and interactions in species divergence.

Learn about muscle fascicle patterns and their role in human anatomy. Our video zeroes in on the convergent pattern found in the pectoralis major. Compare this with other muscle types like the biceps brachii and gluteus maximus to deepen your anatomical knowledge.

Explore stromatolites, the oldest indicators of life on Earth formed by microbial actions. Understand their presence in shallow marine environments and their connection to early eukaryotic life.

Discover what happens in your body after a hearty meal! Learn about the concept of 'distension' and how nerve cells act as messengers to your control center, orchestrating the digestive process.

Explore active and passive transport and understand how ion pumps and phagocytosis fit in. Discover endocytosis as an active transport where cells engulf particles. Differentiate between active transport mechanisms and passive methods like facilitated diffusion.

This video provides a comprehensive explanation of mucous and serous membranes, defining their characteristics and addressing statements about their epithelial types, functions, and exceptions.
