Homeostasis MCQs
Hello students, our next topic of MCQ is ‘Homeostasis’. The term is first defined by Claude Bernard in 1865. Homeostasis is a maintaining constant internal environment. It is also important to keep body temperature at around 37°C and it is also important to keep blood sugar level constant along with levels of ions and water. Even bodies blood pressure needs to be monitored.
