Question

Which of these statements is true regarding ectothermic and endothermic regulation? only endothermic regulation requires a sensor only endothermic regulation requires an integrator only endothermic regulation requires an effector ectothermic regulation requires sensors and integrators, but not effectors both ectotherms and endotherms require sensors, integrators, and effectors Draw

Answer 1

The answer is options 1, 2 and 3

The statements 1, 2 and 3 are true

1 - Only endothermic regulation requires a sensor

2 - Only endothermic regulation requires an integrator

3 - Only endothermic regulation requires an effector

Endotherms are animals that produce their own body temperature through metabolic processes. They are warm-blooded animals. Endotherms maintain constant body temperature and do not dependant on the external temperature. The body temperature of the endotherms does not vary with external temperature.  Endotherms are also called homeotherms. Hemeotherms are animals that maintain constant body temperature. Homeostasis is the mechanism through which the animals maintain a constant or stable internal environment that independent of the external environment. The components of the homeostasis are sensor, integrator, and effector. The sensor detects the changes in the environment and send signals to the integrator. The integrator compares the data from the sensor and the setpoint. Effector makes the condition back to the setpoint

Ectotherms are animals that do not produce their own body temperature and dependent on external heat sources. They are cold-blooded animals. Ectotherms have a variable body temperature. The internal body temperature of the ectotherms changes with the external environment. They are unable to control their temperature metabolically. They regulate their body temperature by behavioral adaptations
