BIOL 154: Animal Biology

Discover the science behind thermoregulation, focusing on endotherms and ectotherms. Understand how internal metabolic processes distinguish endotherms, while ectotherms rely on environmental factors. Highlighting the adaptations each group has evolved to thrive in their habitats.

Discover the concept of negative feedback loops in biological systems, where balance is maintained by counteracting changes. Explore the four key components: Stimulus, Sensor, Control Center, and Effector, through examples like blood sugar regulation. Uncover how these loops play a crucial role in keeping our body systems in harmony.

Explore the concept of semiconservative DNA replication, where each new DNA molecule retains one original strand. Understand the significance of this mechanism in ensuring accurate genetic information transfer across cell generations.
