Unit 4 Review - Homeostasis

Mr. Andersen reviews homeostasis, covering feedback loops, behavioral and physiological responses, and regulation mechanisms like blood glucose and thermoregulation. He discusses the impact of biotic and abiotic factors, plant and animal defenses, and cell differentiation. The video concludes with environmental sensing and evolution, emphasizing natural selection.

Explain the difference between behavioral and physiological responses to environmental changes.

What is osmoregulation and how do the kidneys contribute to this process?

What are biotic and abiotic factors? Provide examples of each.

How does natural selection relate to homeostasis in organisms?
