Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following is an example of HOMEOSTASIS?
A
Hypothalamus/ Pituitary/ Thyroid Axis’ negative feedback loop
B
Hormonal control of the onset of puberty
C
Nervous system regulation of heart and breathing rates
D
All are examples of homeostasis
Explanation: 

Detailed explanation-1: -Body temperature control in humans is one of the most familiar examples of homeostasis. Normal body temperature hovers around 37 °C (98.6 °F), but a number of factors can affect this value, including exposure to the elements, hormones, metabolic rate, and disease, leading to excessively high or low body temperatures.

Detailed explanation-2: -Examples include thermoregulation, blood glucose regulation, baroreflex in blood pressure, calcium homeostasis, potassium homeostasis, and osmoregulation.

Detailed explanation-3: -Three examples of homeostasis are: Body temperature regulation. Blood pressure regulation. Blood sugar regulation.

Detailed explanation-4: -Whether you’re lying in the summer sun or playing in the winter snow, your body temperature only changes by a degree or two. That’s an example of homeostasis being maintained. When you get shivery in the cold, or sweat in the summer, that’s your body trying to maintain homeostasis.

Detailed explanation-5: -For an ecosystem in homeostasis, things change all the time. For example, let’s say we have a really simple ecosystem: lions eat gazelles, and gazelles eat wild grasses. If, in one particular year, the population of lions increases, the population of gazelles will decrease because there are more lions hunting them.
