BISC 208014: Introductory Biology II

Discover how humans adapt to cold environments through thermoregulation processes. Understand the body's heat conservation and generation mechanisms. Learn why certain physiological responses occur in cold conditions.

Explore the spectrum of movement in joints, from immovable synarthrotic to freely movable diarthrotic. Understand how these classifications correspond to fibrous, cartilaginous, and synovial joint types.

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.

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.
