BIOL 120: Biology I

Understand the anatomical significance and position of the lumbar region within the spinal structure. This video explains how the lumbar region which constitutes the lower back interacts with other areas like the popliteal and umbilical regions. Gain a clear perspective on its role in supporting body weight and its location relative to other spinal sections

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.

Explore the fascinating realm of organic chemistry and its emphasis on carbon compounds. Understand how organic molecules, pivotal to life, are intricately composed. Gain insight into the properties and relationships that make these compounds essential.

Learn about muscle fascicle patterns and their role in human anatomy. Our video zeroes in on the convergent pattern found in the pectoralis major. Compare this with other muscle types like the biceps brachii and gluteus maximus to deepen your anatomical knowledge.

Discover how our brain interprets the scent of smoke differently based on context. Compare reactions in an open campfire setting versus an enclosed residence hall. Understand the underlying mechanisms of olfactory fatigue and context-driven alarm responses.

Discover the intricacies of hyperventilation, its impact on the body's CO2 levels, and the resulting respiratory alkalosis. Understand the triggers, physiological implications, and how controlled breathing and meditation can help manage this condition.
