BIOL 1040: Introduction to Biology

Gain a clear understanding of chemical equilibrium, where reactant and product concentrations stay constant due to equal forward and reverse reaction rates. Dispel common misconceptions about equilibrium, such as concentration equality and reaction reversibility.

Uncover the vital role of the kidneys in blood filtration and electrolyte balance. Understand the significance of the glomerulus, Bowman's capsule, and renal structures in the filtration process. Grasp the journey of filtrate as it becomes urine within the renal system.

Unlock the basics of the anatomical position, a crucial standard in medical and anatomical studies. This video clarifies the key differences among prone, supine, and standing positions and why they're not the anatomical position.

Learn about the path of blood flow in the mammalian heart and circulatory system. Discover how oxygen-rich blood from the lungs enters the left atrium and understand why other statements about blood flow are incorrect.

Learn the distinctions between dispersal and vicariance in biology. Understand how organisms' movements and environmental changes play crucial roles in allopatric speciation. Grasp the differences between movement across existing barriers and the creation of new barriers.

Discover the concept of adaptation in this video, where we evaluate four scenarios to determine which represents a heritable trait enhancing an organism's survival in its environment. Learn how the webbed feet of a duck exemplify a true adaptation, enabling it to thrive in its habitat.
