  1. Essential knowledge 2.D.3: Biological systems are affected by disruptions to their dynamic homeostasis. http://www.youtube.com/watch?v=s8jhJXgC-bk

  2. a. Disruptions at the molecular and cellular levels affect the health of the organism. • To foster student understanding of this concept, instructors can choose an illustrative example such as: • • Physiological responses to toxic substances • • Dehydration • • Immunological responses to pathogens, toxins and allergens • b. Disruptions to ecosystems impact the dynamic homeostasis or balance of the ecosystem. • To foster student understanding of this concept, instructors can choose an illustrative example such as: • • Invasive and/or eruptive species • • Human impact • • Hurricanes, floods, earthquakes, volcanoes, fires • • Water limitation • • Salination
