Question

Which of the following options exemplifies a behavioural means of homeostasis?
A. A man sweating profusely in a hot room
B. A rhino covering itself in mud to keep cool
C. A desert lizard basking in sun too increasing its body temperature
D. Both (B) and (C)

Answer 1

Hint: The tendency of an organism to resist the change in order to maintain a stable or relatively constant body temperature or internal temperature is called homeostasis. The process of homeostasis involves a negative feedback mechanism.

Complete answer:
The ability of an organism to maintain a relatively stable internal state that persists despite the changes taking place in the outside world is called homeostasis. Some of the examples of homeostasis are the human body regulates the temperature by maintaining the concentrations of the different ions such as calcium, potassium or sodium. The temperature of the human body is maintained at the core temperature of $37$degrees Celsius. When the body absorbs a lot of heat and then the thermo-sensors in the skin and brain regulate it creating a chain reaction that creates sweating in the body and this is followed by shivering and reducing blood circulation in blood.
There are many phenomena occurring in our surroundings that help to understand that many organisms show behavioural changes or adaptations that help them to adjust to the environment.
From the above explanation it is clear that a rhino covering itself in mud to keep cool is an example of homeostasis. Also, the other example for homeostasis is the desert lizard basking in sun to increasing its body temperature So, the correct answer is option D. which states that option B. A rhino covering itself in mud to keep cool and option C. A desert lizard basking in sun too increasing its body temperature.

Hence, the correct answer is option (D)

Note: Homeostasis is important as it regulates the stable body temperature in living beings. It helps to detect changes and to react to those changes and restore the stability. Some of the examples of homeostasis are the sweating in living organisms that helps in regulating the body temperature in living beings and the other example is the concentration of body salts and minerals in the body.
