    Has profanity
    animal development
    development biology
    Hank explains the way in which organisms grow and develop. He covers how to determine the complexity of an organism and illustrates that the digestive tract is the first part of the organism that develops.

  • Crash Course: Biology: Eukaryotic Transportation and Building

    golgi apparatus
    endoplasmic reticulum
    cell biology
    Hank provides an overview of the function of the Endoplasmic Reticulum (ER), Ribosomes, Golgi Apparatus, and Lysosomes. He covers the two different types of ER, smooth and rough, and explains how all of these organelles work together.

  • Crash Course: Biology: ATP

    cellular respiration
    adenosine triphosphate
    Hank explains how Adenosine Triphosphate (ATP) is used in the body. He describes ATP as the currency of biological energy.

  • Crash Course: Biology: Photosynthesis

    Hank explains in-depth the series of reactions that take place for a plant to produce food for itself, also known as photosynthesis. This video also explores the prerequisites (sunlight, carbon dioxide, and water) of these reactions. Key Words: Xylem, Stomata, Chlorophyll, Chloroplast, Thylakoid, Photoexcitation, Photosystem II, Electron Transport Chain, Cytochrome Complex, ATP 

  • Crash Course: Biology: The Calvin Cycle

    calvin cycle
    carbon fixation
    Hank explains the Calvin Cycle, the light-independent reactions that occur within a plant to turn sunlight, water, and carbon dioxide into energy. The Calvin Cycle is broken down into three steps: Fixation, Reduction, and Regeneration.
