BIOL 124: Human Physiology & Anatomy I

Explore the relationship between monomers and polymers, focusing on nucleic acids and their building blocks. This video clarifies the distinctions between various biological molecules and their basic units, emphasizing the critical role of nucleotides in nucleic acids.

Discover the fundamentals of the respiratory system and the primary muscle behind inspiration. This video breaks down the physiological process of breathing, the key role of the diaphragm, and why other muscles don't initiate breathing.

Learn about mouse genetics and the implications of dominant and recessive genes on coat color. We'll use a Punnett square to predict offspring coat patterns by crossing two heterozygous mice. Learn how phenotype ratios like 9 Agouti: 4 white: 3 black help us understand genetic outcomes.

Unravel the mysteries of food chain lengths by analyzing various factors. We spotlight the 10% rule in ecology, emphasizing how energy transfer inefficiencies mold ecosystem structures and functions.

Discover the wonders of parthenogenesis a form of asexual reproduction in our latest educational video. Understand how an egg cell can develop into an embryo without fertilization. Learn the key differences between parthenogenesis and other forms of asexual reproduction like budding and sequential hermaphroditism.

Discover the concept of negative feedback loops in biological systems, where balance is maintained by counteracting changes. Explore the four key components: Stimulus, Sensor, Control Center, and Effector, through examples like blood sugar regulation. Uncover how these loops play a crucial role in keeping our body systems in harmony.
