BIOL 3409: General Ecology

Explore the characteristics that distinguish normal cells from cancer cells in this informative video. Learn how normal cells perform specialized functions for overall health, while cancer cells grow uncontrollably. Discover why cancer cells lack differentiation, ignore reproduction control signals, and their connection to the absence of radical scavengers, all leading to their uncontrolled proliferation.

Explore the Evolutionary History of Invertebrates: Are Beetles Related? Discover the intricate web of invertebrate evolution, dating back over 500 million years, and why beetles and their invertebrate counterparts do not share a common ancestry.

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.

Uncover the fundamentals of human muscle contraction and anatomy in this lesson. Highlighting the distinct roles of muscle origin and insertion we clarify their functions in movement. Learn why the muscle origin is the cornerstone of stability during contraction anchoring our body mechanics.

Explore the intricacies of DNA replication and the pivotal role of Okazaki fragments. Understand the difference between the leading and lagging strands. Dive deep into the mechanisms that drive this life-sustaining process.
