Negative feedback mechanism is the characteristic of which class?
Correct answer: D. Class Mammalia
- A. Class Fish
- B. Class Amphibian
- C. Class Reptilia
- D. Class Mammalia
Explanation
Negative feedback mechanisms are a characteristic of Class Mammalia. A negative feedback mechanism is a regulatory process where the response to a stimulus reduces or stops the stimulus, maintaining stability or homeostasis. This mechanism works by counteracting a change to return a system to its set point, similar to how a thermostat turns off the furnace once the room reaches the desired temperature. Examples include the body regulating blood glucose, body temperature, and the secretion of hormones.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
