BIL 150: General Biology

Uncover the fundamentals of human muscle contraction and anatomy in this lesson. Highlighting the distinct roles of muscle origin and insertion we clarify their functions in movement. Learn why the muscle origin is the cornerstone of stability during contraction anchoring our body mechanics.

Discover the properties and significance of methane (CH4), from its atomic structure to its pivotal role in industry and the environment. Uncover how carbon and hydrogen atoms form covalent bonds, making methane a key component of natural gas.

Explore the nature of compounds in chemistry, focusing on potassium chloride (KCl) and its dissociation. Understand the distinctions between salts, acids, bases, and buffers. Dive into the characteristic behaviors of each to identify the true nature of KCl.

Discover how the protein coat from pathogenic cells can transform nonpathogenic cells, the surprising role of heat-killed pathogenic cells in causing pneumonia, and the transfer of pathogenic traits from one cell to another. Join us on this journey of scientific exploration as we unravel the mysteries of bacterial transformation and more.

Unlock the secrets of muscle anatomy to answer questions about a muscle's function and characteristics. Learn how the location of a muscle's insertion and origin impacts its action name and force of contraction. Enhance your knowledge about the human body's intricate mechanisms

Learn about male pattern baldness as we break down the science behind shrinking hair follicles and their effects on hair thinning. Learn why bald men still have hair follicles and what happens to them over time. Ideal for anyone keen to understand the biology of hair loss.
