BIOL 1011: A Survey of Life Laboratory

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 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 how viruses replicate and the various ways in which new viruses emerge. Understand the importance of mutation, cross-species transmission, and the significance of wider spread in host species for disease control strategies.

Discover the pivotal role of decomposers and detritivores in forest ecosystems. Understand the catastrophic consequences of their absence, from biomass accumulation to biodiversity loss. Learn how these unsung heroes maintain forest health and sustainability.

Explore the effects of isotonic, hypertonic, and hypotonic solutions on plant and animal cells. Understand water movement, solute concentration dynamics, and the resulting cellular changes, including turgidity in plants and crenation or lysis in animals.

Uncover the key roles of the cerebral cortex, from cognition and memory to emotional regulation. Compare its functions to those of the hypothalamus, particularly regarding circadian rhythms. Get the answer to what the cerebral cortex doesn't govern.
