BIOL 1110: Biology 1

Explore the significance of tracking same-age cohorts in population ecology. Learn how it aids in understanding birth and death rates, predicting population trends, and uncover the reasons behind this crucial ecological research practice.

Explore the world of microbiology in this video as we investigate the processes that lead to genetic variation in bacterial populations. Learn about transduction, transformation, conjugation, and mutation, and discover why meiosis, a process occurring in sexually reproducing organisms, is not a source of genetic variation in bacteria.

Discover the pivotal genetic change behind the evolution of tetrapod limbs, focusing on a specific shift in the Hox gene expression. Unravel the significance of this change and its role in the spatial organization of body parts.

Explore the world of proprioceptors specialized sensory receptors in joints muscles and tendons that help us sense body movement and position. Understand the key types such as muscle spindles tendon organs and joint kinesthetic receptors. Learn why tactile discs are not considered proprioceptors even though they are sensory receptors

Uncover the microscopic intricacies of compact and spongy bone structures. Learn about osteons, trabeculae, and the vital role of osteocytes. Dive into the balance of strength and functionality bones provide to our body.

Explore the intricacies of muscle contraction and the pivotal role played by elements like Calcium, Sodium, Potassium, and Chloride. Learn how Calcium directly triggers contraction by interacting with troponin and actin filaments. A thorough breakdown of each element's unique contribution to our body's movement.
