Homeostasis Preview

Mr. Anderson explains the concept of homeostasis, emphasizing its role in maintaining a stable internal environment amidst external changes. He discusses abiotic and biotic factors, feedback loops, and the importance of both behavioral and physiological responses. The video also highlights the influence of evolution on these processes, using examples like temperature regulation and childbirth to illustrate negative and positive feedback loops. The discussion extends to how organisms adapt through evolution, with examples from plant and animal defenses.

What is a positive feedback loop, and how does it differ from a negative feedback loop?

How do behavioral and physiological responses differ in maintaining homeostasis?

Discuss how evolution influences the responses of organisms to environmental changes.
