Characteristics and Molecules of Life

The video tutorial introduces biology as the study of life, explaining the characteristics that define living organisms. It covers the acronym 'EGG CHARR' to help memorize these traits, such as evolution, genetic code, growth, cells, homeostasis, energy use, environmental response, and reproduction. The tutorial also delves into the molecules of life, including carbohydrates, lipids, proteins, and nucleic acids, explaining their roles and structures in living organisms.
