B)remain within certain limited ranges
C)increase when the body is stressed
D)fluctuate greatly between very high and low values

Question

Quizplus · Accepted Answer

Homeostasis is the maintenance of a stable internal environment in the body. This means that concentrations of water, nutrients, and oxygen, as well as heat and pressure, must remain within certain limited ranges to ensure proper bodily function. If these variables were to decrease steadily or fluctuate greatly between very high and low values, homeostasis would not exist. Similarly, if they were to increase when the body is stressed, this would also disrupt homeostasis. Therefore, the best choice is B, as it accurately reflects the conditions necessary for homeostasis to occur.
