BIOL 1011: General Biology

Discover the debate between Intelligent Design (ID) and evolutionary science as they clash over the complexity of biochemical pathways in nature. Explore the concept of guided vs. unguided evolution and how diverse pathways challenge the ID perspective.

Discover the mechanics of voltage-gated Na+ channels and their role in neuron activity. This video breaks down key neuronal terms like resting potential and threshold to explain precisely when these channels open. You'll come away understanding that voltage-gated Na+ channels open at the threshold state initiating an action potential.

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

Discover the pivotal genetic change behind the evolution of tetrapod limbs, focusing on a specific shift in the Hox gene expression. Unravel the significance of this change and its role in the spatial organization of body parts.

Get insights into the role of lysosomes in different cell types. Find out which cell is the ideal choice for studying these powerful digestive organelles and why.

Unravel the intricacies of mitosis by identifying each phase and their characteristics. Highlight the process that is not a part of mitosis, emphasizing the importance of DNA replication.
