Which of the following statements best describes the term Homeostasis...
Homeostasis
Maintaining a relatively constant internal environment within an organism's cells is referred to as homeostasis. This process is essential for the overall well-being and functioning of the organism.
Key points:
- Homeostasis involves the regulation of various factors such as body temperature, blood sugar levels, pH levels, and water balance.
- The goal of homeostasis is to keep the internal environment stable despite changes in the external environment.
- The body achieves homeostasis through feedback mechanisms involving sensors, control centers, and effectors.
- For example, when body temperature rises, sensors in the skin and brain detect the change and send signals to the hypothalamus (control center), which then triggers mechanisms like sweating to cool down the body.
- Similarly, if blood sugar levels drop, the pancreas releases glucagon to raise blood sugar levels back to normal.
- Homeostasis is crucial for the survival of organisms as it ensures that cells can function optimally within a stable internal environment.
In conclusion, homeostasis is a fundamental process that allows organisms to maintain stability and adapt to changes in their surroundings. It is a complex and intricate system that involves various feedback mechanisms to keep internal conditions within a narrow range for optimal functioning.

Which of the following statements best describes the term Homeostasis...
Homeostasis any self-regulating process. It is the act of maintaining a relatively constant internal environment within an organism's cells. Cells function most efficiently in a certain range of conditions and as the environment changes around them, they constantly work to keep their internal environment in an optimal condition. Cells are working to maintain factors such as water concentrations, salt and sugar, the temperature within the cell, and oxygen concentrations. So, statement (a) is correct.
If homeostasis is successful, life continues; if unsuccessful, disaster or death ensues. The stability attained is actually a dynamic equilibrium, in which continuous change occurs yet relatively uniform conditions prevail. The control of body temperature in humans is a good example of homeostasis in a biological system. In humans, normal body temperature fluctuates around the value of 37 °C (98.6 °F), but various factors can affect this value, including exposure, hormones, metabolic rate, and disease, leading to excessively high or low temperatures.
Therefore, the correct answer is (a).
