1. Fish respiration lab

2. Class data

3. What can we conclude after looking at the data? Temperature will affect the respiration rate of goldfish. Goldfish respire at a slower rate at lower temperatures and a faster rate at higher temperatures.

4. Why does respiration rate change with temperature? The amount of oxygen at lower temperatures is less than the amount of oxygen at higher temperatures. Cause : Temperature of goldfish water changed. Effect : Fish respire differently at different temperatures.

5. Fish changing respiration rate is an example of maintaining homeostasis Fish need to maintain oxygen levels & body temperature! o Respiration changes to maintain homeostasis! Homeostasis – maintaining internal balance in the body o Body temperature o Oxygen levels o pH

6. Respiration vs. Cellular respiration

7. If we did a similar experiment with a human, would it field the same result?

8. Body temperature & environmental temperatures of different organisms. River otter = mammal Human = mammal Conclusion after observing this data?

9. Humans regulate their body temperature. Regulated through metabolic processes (energy lost as heat) Fish and other animals rely on the environment to regulate body temperature.

10. Homeostasis is maintaining stable internal environment in the body. Keep body/cells working properly! o pH and temperature sensitive! Break enzymes down when it is changed. o ALL organisms maintain it, just in different ways.

11. How do humans maintain homeostasis?
