Two Categories of Organisms: Poikilotherms and Homeotherms

The probe measures the concentration of oxygen in the chamber in milligrams / liter. The detector sends data on the oxygen in the tank to a computer program called LoggerLite. First, create a flowchart (Figure 1) to organize and minimize potential errors. After washing hands to remove pollutants, 400 ml (ml) fish water was collected. 200 ml of distilled water in the oxygen chamber was replaced with 200 ml of fish water and the probe was warmed for 10 minutes.

There are also two terms that further complicate this problem. The first one is an isothermal animal in which body temperature is kept constant, and the second is a temperature change suitable for animals whose body temperature fluctuates depending on the environment. (If a creature changes behavior to maintain body temperature in the face of a harsh environment, it may not be hypothermia, not body temperature.) As can be inferred from the above definition, it is an endotherm There is no need for body temperature reptiles that have lower temperature blood than sexual mammals to follow. For example, the blood of a desert lizard sunbathing in the same environment temporarily gets warmer than the blood of a mammal of the same size, but the temperature of the lizard drops with sunset.

Reptiles are animals that change body temperature and body temperature. Because of its limited ability to control body temperature, body temperature is usually limited to certain places. However, except for Heterocephalus glaber, mammals are endothermic and thermostat. This provides the advantage for them to explore various environments.

The thermostat has the ability to maintain its internal ambient temperature at a steady level, while the varistor can not adjust its internal ambient temperature. When body temperature tries to adjust based on outside temperature, changes in body temperature cause changes in body temperature. For example, some sunglasses that adjust body temperature have sunbathing to adjust body temperature by warming the body. The thermostat tries to adjust the body temperature by the feedback mechanism of the body system

Temperature homeostasis is one of the most important examples of homeostasis in organisms. Body temperature homeostasis keeps the animal's body temperature at a stable temperature. That is, it helps the animal's body temperature to overheat and get cold. Animals with balanced body temperature (birds and mammals) are called warm-blooded animals. Other animals whose body temperature changes are called temperature change animals. The thermostat normally keeps body temperature around 37 ° C just as it is also called warm-blooded animal. If they are immersed in the sun for a while, their blood will be very warm
