BIOL 326: Ecology

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

Explore the world of microbiology in this video as we investigate the processes that lead to genetic variation in bacterial populations. Learn about transduction, transformation, conjugation, and mutation, and discover why meiosis, a process occurring in sexually reproducing organisms, is not a source of genetic variation in bacteria.

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.

Unlock the language of genetic history with our guide to understanding pedigrees and their symbols. Learn how to interpret squares circles and lines to track inheritance patterns for traits and diseases.

Dive into the world of cellular respiration, where glucose transforms into energy-rich ATP. Unpack the crucial steps that occur mainly within the mitochondria, resulting in the release of carbon dioxide and the production of the cell's primary energy currency. Decode life's foundational energy process and its significance in cellular functions.

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.
