Question

Answer 1

Answer:

3.)A person shivering when their body temperature is low.

7.)Ants moving within their mounds depending upon the time of day

1-A plant bending toward a light source.

.-Iguanas laying in the sunlight if their body temperature is low.

.-A unicellular organism beating microscopic hairs to escape a chemical pollutant in its environment

.-Birds migrating when seasons change.

The maintenance of relatively constant internal environment of an organism is called  Homeostasis.It is an automatic regulations of the body systems and organs controlled by the brain and some receptors, specific for certain body fluctuations.E.g Thermoreceptors Chemoreceptors etc.

The fluctuations in the body internal systems must be controlled within a narrow limits, for existence of living organism.The brain receives inputs from the receptors, and the outputs from the brain ensures the  homeostatic control.

The above examples are typical homeostatic responses by the organisms involved, because the inputs from the receptors  send signals to the brain ,and the organisms  responded to these with the example above.
