Homeostasis

• allows for a wildly fluctuating internal environment

• is impossible in vertebrates

• is the maintenance of a relatively stable internal environment and often incorporates a form of feedback regulation

Biologists study the effect of different temperatures on breathing in goldfish. The number of times the fish open their gills determines how many breaths the fish take. The biologists place goldfish in three different fish tanks. The tanks are at different temperatures. They count the number of breaths taken in five minutes. Their data is given in Table 1. Why are the breathing rates of the fish different in each tank?

• Warm water has less oxygen, so they have to breathe more often to get the needed oxygen.

• Warm water speed up a fish's metabolism, making it need more oxygen (which it gets by breathing faster).

• Fish alter their breathing rate to adapt to changes in their environment, helping them maintain homeostasis.

• Fish breathe faster in colder water to avoid freezing.
