Question

Many different feedback mechanisms have evolved over time. These mechanisms allow an organism to respond to changes in both its internal and external environment. Select an organism from those you have learned about and using one or more complete sentences, describe how a specific feedback process works within that organism. Include how the feedback specifically helps the organism maintain homeostasis.

Answer 1

Answer:

Regulation of body temperature in human occurs through negative feedback system.

Explanation:

Lowering down the body temperature below the average range is followed by shivering of skeletal muscles to generate heat and to bring back the body temperature to normal range. Similarly, when the body temperature is higher than normal value, the body's thermostat stimulates dilation of blood vessels to allow more blood flow bear the body surface to loose the heat. So, regulation of body temperature in human is an example of negative feedback system

Answer 2

In humans, one feedback mechanism is to either sweat or shiver, depending on the body temperature. Sweating helps lower the body's temperature, and shivering helps raise the body's temperature.
